I'm pretty fed up and heartbroken as it goes.
I broke up with my ex girlfriend last week as I could no longer trust her, she was constantly lying to me and the arguments never stopped as a result of my trust issues because of it.
I did everything for this girl, she lost one of her parents to cancer when we first got together and I was there to guide her through it, i practically (it felt like) glued her life together. I was with her for a year, I took her virginity and was her first proper boyfriend and as soon as the ordeal with her loss was over I just felt like I was being treated like crap all the time.
So I'd had enough and broke it off a week ago, and already it looks like her and another guy are talking, baring in mind she was the one accusing me of apparently moving on too quickly? They appear to be liking each others photos and getting quite serious. They've known eachother since high school but only seem to be getting together now. I realise he's probably a rebound, but really this soon? She even used to like his photos whilst we were together, nothing wrong with that, but now this is happening it makes me wonder whether something was happening behind my back whilst we were together?
I did everything for this girl, dates, bought her gifts and she bought me gifts, took her to romantic places, I was literally the best version of me and the best boyfriend I could have possibly been to her.
Literally have no idea what to do. It just feels like everything i did for her, including during her loss was all for nothing and that she couldn't care less.
