Did I do the right thing?

-So it's a long story but I'll try to sum it up quickly. I met a guy two years ago that I fell head over heals for. It felt like we were on the same page, had the same sense of humor, played like children, and the chemistry was unheard of. After a couple weeks I started noticing he had a texting addiction...never could put down the phone when we were together...etc. I thought at first, no big deal. Then one day we were having lunch and he was texting someone and I jokingly asked him if he was texting a girl. He got all defensive and said of course not etc which kinda put me off ease, but I tried to think nothing of it. Then I noticed he had a lazy eye, and when we went out he had all these sleazy looking girls who seemed to be a little more comfortable than friends with him. When I asked him about the nature of these relationships he would get mad and say I didn't trust him which I took in and thought it must be true because I did have some trust issues...maybe I was just seeing into something too much. Then on Valentines day, we have a beautiful night, and he gets all mad at me for my beliefs on vegetarianism and thinks Im against him, which im not...I thought it was nothing so I wasn't expecting him to break up with me that night, which totally broke my heart. The next day he left a letter in my mailbox saying he thinks he may have made a mistake. I am confused at this point but I love him so I keep the interaction going. We still were making love even though we were broken up, so I thought that, in a way...there was still some sort of loyalty. I was wrong. One of the nights he said he was going to come up to see me he kept putting it off, and off, and off. I had dressed up and was waiting for him and ended up passing out in my own tears. The next day he runs to my house in tears because he slept with some model that we was on sortof a date with the night before. I lost my mind and he called the cops on me because he was worried about my well being which was horribly invasive...when he got there the cops were gone and I was heartbroken and furious but still took him back. At that point, I did have trust issues with him. Certain things he would do would give me panic attacks. And when ever he checked his phone repeatedly when we were supposed to be having quality time my heart would race and I would panick and start asking him questions. He progressively got more and more mad at my questions and kept saying I had trust issues which I started to believe more and more because I did have a history of trauma so...But then there would be times when he would back out of plans because something would come up or would be four hours late and my friend kept telling me about this book about emotional abuse and at some point I wasnt sure if it was me with the trust issues or him with the actions that made me batty. I felt like I could not rely on him and that he was never there for me emotionally, except for on his own time. We had some of the most beautiful times which is why I think i let it go on so long...we even moved in together for four months but it went awful because we moved too far away from my friends and school and he would come home late at night and was late for my birthday by four hours even though he knew I had rented a hotel an hour away and was spending the day in it alone and wanted to be with him. It turned out he was building me my birthday gift, yet the next day I accidentally saw it without him because I had to use the restroom and HE got mad, saying I ruined everything even though I tried to say Id pretend like I hadnt seen it. At this point I was in a deep depression and wanted to talk to him but he would get angry and walk out on me or call me crazy and I had a complete nervous breakdown and he moved out and left me alone in a house in the ghetto. I said a bunch of angry things due to his back and forth commitment that I really regret. We broke up. I kept trying to work it out, go to therapy, etc. He gave me mixed messages and I started to have commitment issues to him. He continued to say he loved me more than any1 in the world, but wanted to date other people. I would watch him to see what was real, because I couldnt understand all the mixed messages. He started dating another girl and has been stringing me along for eight months. I finally told him we can't talk anymore and I blocked his number because the blame always seems to end on me and I feel like a battered woman. I still love him so much but when I look back at the way hes treated me I think, no wonder I've been acting crazy...? Keep in mind this is a lot of negative stuff, when there was just as many beautiful things that he has done/ I have done I just want to understand why I feel like I have lost all my sense of self esteem through this...I want to figure out what the heck the lesson is so I can stop hurting....Positive feedback would be helpful! Thankyou.
