This is a list that has the potential to be endless! A few come to mind: 1. By just disappearing. No notice of the "breakup" from the breaker. No call, no in person let down, no letter, no e-mail. . .nothing. Been there, done this. We dated for 2 years. He ended his tour with the Air Force here and didn't bother to tell me. Not very nice or mature. 2. By overlapping your relationships and pulling the ol' "I've found someone else". End one relationship before moving on to the next. Anything less is kind of sleazy. 3. Ending it by phone or e-mail. Unless you have a valid reason to be afraid (say he/she is prone to chasing you with a knife), relationships should be ended in person. 4. By sabotaging the relationship. There are many ways to do this. For example, you don't want to be the bad guy or gal so you arrange to be caught cheating thus forcing (in most cases) the other person to initiate the breakup. Or you just try to be the worst partner you can be to force the same thing. Mind games are not attractive. I'm sure there are many more, but this is a start. :)

Ah...allow me to share another chapter from my personal book of bad relationships! I would say the worst way to do it is through e-mail. It is cold, callous and lacks any kind of emotion. I was in a relationship with someone for six months, and then seemingly over night she decided she was done with the relationship. So, as Anderson777 had pointed out in her answer, I was victim to number 3 and 4 on her list: The e-mail and the sabotage. She stopped calling me, and when I tried to contact her on AOL Instant Messenger, she blocked me and then sent me a cold, heartless e-mail to end the relationship. Too much of a coward to do it in person, I suppose. As for the sabotage, she basically was unncessarily mean and anti-social with me for a few days leading up to it, I guess basically just trying as hard a she could to end it. Of course the idiot wanted to 'be friends afterward' to which I disagreed. The point is, e-mailing your break-up is just cruel. It doesn't allow the person who is receiving the break-up e-mail to interject their viewpoints or arguments into the situation. You can't get a word in edgewise, and basically you're at the mercy of the e-mail, completely unable to potentially salvage or convince your other not to end the relationship. By lacking emotion it makes the breakup seem much more harsh than it may actually be. Basically, it just isn't fair to the person who is on the receiving end of the breakup on many levels. Its like a 'Dear John' letter...you receive it and there's nothing you can do about it. Having experienced it, I don't really think anyone deserves it unless it was a really, really bad relationship. In my own personal case, I certainly didn't deserve it, but it was a totally one sided relationship. Sorry to be so preachy...just remember that the e-mail breakup (a "To John" rather than "Dear John") is probably one of the most heartless ways to do it. Although, as Andeson777 pointed out, the plain disappearence is pretty bad too...that's just plain cowardly.

Leave it on their answering machine without an explanation and never speak, write or communicate with them again.

The very worst way, which happened to me was when she decided that it was over, she told everyone else EXCEPT for me. So when I would come around to see her she always seemed to be busy or pre-occupied about something.. One day I offered to take her out to lunch because we had not talked in quite some time and she was with her closest friend who whispered in her ear and started giggling. She told me that she would be tied up all day so I didn't really bother her about it. But when her friends were around they would look at me very strange and start whispering to each other. And somehow I couldnt help but thinking that there was something that I didnt know but OUGHT to know. I couldnt tell if they were keeping a secret from me or if I just had a nasty spot on my shirt that I wasnt aware of.. or maybe I got an ink stain on my forehead but nobody had the guts to tell me.. Whatever it was, something didnt seem right. And a couple of times I had asked her if everything was ok and how she felt about us and the relationship. She didnt exactly say everything was fine but at the same time she wasnt as forthright as she could have been. So when I started asking her friends about her and how I was concerned that my phone calls werent being returned and if they knew why she was acting so strange. One of her friends said, "oh, well I thought you guys were just friends and not really together anymore" Finding that out really made me angry. I didnt mind so much that she met another guy and liked him better but I was really angry about the fact that she never said anything about it and figured that I would go away if she ignored me long enough.

Curious question. Are you wanting to break up with someone in the worst possible way, and really hurt them? That answer for me is coming home to hear what sounds like screaming but turns out to be some wild sex they are having in my living room. That's the most cowardly, hurtful thing that someone can do their partner in my opinion.

Over the phone, by letter, at a restaurant, at your mom,s house, at a movie.

Worst I've heard, On their 20th anniverary a card: Honey, the last 20 years have been wonderful, but I don't want to spend the next 20 with you.

I once knew a guy that told his wife she needed to get a job. She thought they needed the extra money so she did. When she came home all excited about the job she had gotten, he told her ,"Now go get an apartment." I thought that really sucked. We were never friends after that.

The worst way to break up with someone if you really want to hurt them is to say it on television or on the intercom.

Also this is wat my boyfriend did. He came to my work office and didn't bother to wait for me. He told my BOSS that he's breaking up with me because i wasn't KINKY and UNIQUE IN BED enough for him!!! My boss came at my lunch break and told me, everyone was listening, that my boyfriend dumped me. Imagine your boss saying, "He said you don't EXPERIMENT ENOUGH" My boss is a guy, and everyone in the office was at lunch.

Avoid the subject and talk in the car, playing a break up song over and over again in the background until it sinks in. A good example might be The Dandy Warhols' "We used to be friends." (The Veronica Mars theme song.) There are many others!

Not telling a person at all and stretching it out 6 years. Letting the love slowly fade away in the worst way.

Pretending everything is okay for years while you know that it's over... then telling them when it's so much harder to move on.

I have been in a relationship for almost nine years. The guy seemed to pick small things to argue about for example the cost of phone calls and abruptly ended a conversation with ' have a good night! that was the last I heard from him. Can you top that one?

cheat on them for a year, then confess everything the day before the anniversary - which happened to be fathers day to a father of 2 and another one on the way... women don't take that too kindly

Always want from other anyway.

My ex-wife ended our relationship by going off of her meds and then accidentally arranging for the mental health air force to fly her back to Canada. I know that's not the worst way so I defer to the dude in the pic below for input on one of the worst: ;)

probably how i did it :(

I dont know how to put videos on here but "text messege breakup" would be it...Check out this video its by (Kelly) http://www.youtube.com/watch?v=XcidD2HFK8M&feature=related

I would hazard at a guess that pushing them in front of oncoming traffic would not be nice.

Let then find you in bed with their brother, then tell him his brother is better. LOL.

Steal their credit cards and go on a shopping bonanza :) yeah, that sucked :D

I broke up with my bf in a christmas card... lol I think we were 11... and barely spoked as it was!! Bet he didn't put that one up!!

I would say over the phone. I think only a coward ends a relationship over the phone, and ignoring you and not ending it officially just letting it fade away... then you do not know where you stand with the person...

Over the phone, in a text message, or through e-mail. Basically, anything OTHER than talking to the person face-to-face.

tell the person you never considered them your boyfriend. i did that and regretted it, so cold.

Text message, on the hone or plan cheating n them so they get the hint ....

This can work....

Sleep with their best friend, in their house on their birthday.

well i would be heartbroken if somebody ended it with a text message or an email. that is how i was dumped, but i knew it was coming so i prepared myself. id also hate to be told by his mates, i had that aswell. men just have a thing about telling females how they feel, AND ITS ANNOYING.

Having a great evening with them and then turning around and saying out of the blue that you've never loved them( after 11 years) and have never wanted children!

wright on there back with suntan lotion were over with or somthing like that and just stay away from them (has to be done at pool or a beach)

murder...not good...

She avoided me for three weeks, but we talked a little bit. And in those three weeks, she met someone else. She told me that they talked a lot. She would be talking to me for like 5 min, then ask if its bad that she was talking to him for two hours. Then we saw each other at a social event and she wouldn't talk to me at all. she grabbed her friends phone to text me AFTER i left, and her friend took the phone back and said, "she says its over." Publicly. Over the phone. Through a friend. And avoidance. I think this one wins...sadly.
