What is wrong with me for him to leave for someone else?

[Marie]

My boyfriend broke up with me because he found someone else. He broke my heart. She is pretty and he always came down on me for the way that I looked. I lost so much weight after I switched my medication because I have epilepsy and I also do crew.

I lied to him one time about texting a guy who took me to homecoming freshman year, I promised I wasnt texting any guys when in fact I responded to the guy. He texted me and I responded and we broke up, but that night I begged for him back. He however, in the six hours we were broken up went to that girl (he had never met) and they planned to take it slow, and be together one day. Even though he took me back after begging him and apologizing and saying I will prove to him that I can be trusted. He has done TERRIBLE things to me. I have only lied one time to him in the course of our two year relationship because I believe in full honesty. I have however made mistakes when telling the truth because some guys have "come on" to me and I have "accepted" the attention because my boyfriend had treated me badly and I told him the way I was feeling that I wanted to accept their attention, in other words, and it made him hurt. I never meant to hurt him. He downloads dating apps, talks intimately with other girls (just once i guess he said), lies about blocking girls, lies about talking to people, insults my features, everything. He broke up with me on my birthday two years in a row. He broke up with me everyday last year because his friends told him to, and I risk everything for him because my parents dont know and if they did, I would have nothing because they hate him and I got my iphone taken last year now I have a non-smartphone (not in trouble anymore and they trust me but they dont know about him), I text him on my laptop, I work so hard for us and I love him with everything I have I cant imagine a wold without him. But he left me for her, they arent dating but the night that we got back together, the morning after he said he needed time to trust me again, just to give him a week and that if he falls in love with her, oh well he deserves better.

I am just trying to give the full story the best I can so that it is not so one sided, he never tells the full story. His lies more than I have ever lied to him, yet he makes me a horrible person. I am a very kind person and I work very hard. I am very very loving and caring and I can't imagine life without him but, I just hate the way I am feeling. I have cried so much. Please help with this, and please tell me what is wrong with the way that I look for him to critique me so much? What is wrong with me? (p.s. weve been together 2 years).
