So I'm in a highschool relationship this is the longest I've been in 6 months this Saturday actually, anyways I've recently moved schools due to parents, okay whatever, at this school one day I was just hanging out with a female friend and decided to wear her sweater for no more than 5 minutes and took 1 picture with it on, I show my girlfriend a couple hours later through messages when I'm home and she says not to do that with any girls sweater again cause she gets jealous, that should've been the end but I asked why and she said what if I did that with a male friends sweater (which most people can agrre is different) anyways I saw her point and said okay I promise I won't do it again can you promise you won't do that with a male friends sweater and she does promise, 5 days later an old friend from the school she went to told me she had been wearing some guys sweater the previous day that obviously was not mine (he even had a picture to go along with his statement) he said she had it on at the very least 2 class periods if not more (2 hours), so she broke a promise and did something she said she wouldn't (not the first time) and she hid something behind my back for the first time ever, what's your opinion on this, literally anything. Thank you for your time reading that long mess
