Hey guys i've recently had a breakup with a 4 month LTR. ( i am 17). She broke up with me because according to her i was not doing as much as she did in the relationship and she had dreams of a perfect boyfriend a couple times and took that as a sign.

She is comepletely right when it comes to me not being invested enough (for her). she would sleep over alot and we would mostly just fuck at my place and watch movies or i would play games. i could foresee the breakup a couple weeks earlier but it still hurt a bit when we broke up even thought i actually had thoughts about breaking up too. So basically she was clingy and wanted me to do things with her that are instagram worthy like going shopping in the city ect, but all we did was basically sleep over together.

she broke up via text and my response was basically "K", but a week afterwards i explained it was a little hurtful even thought i wanted it to end (mistake?). Now i am getting my shit together by working more and reading up books ect.

but as soon as we broke up she would go around hooking (kissing) up with alot of guys according to some female friends of mine, what does this mean? that i emotionally fucked her up or something? And what should i do with her in the future?
