I'm A Crazy Ex-Girlfriend???? Or Just Hurt? HELP ME!?

So Ill try to wrap up 2 years as quickly as possible. My ex came into my life confessing his undying love for me. We moved very fast! We got a place together, and he got a ring and proposed and things were great. Until everything went wrong. He began to contact his ex-wife and many other women in an inappropriate manor. He became cold, mean, selfish and abusive. The more I tried, the more he seem to have hated me and pushed me away for mos. We were on an ongoing roller coaster. I had to move out and it was hard because I was in school and working part time and he was the sole provider so I had to struggle to maintain after he decided he didnt want to be with me. We then got back together for two mos and broke up again about a week ago. During our break up I was furious with anger and I felt cheated, lied to, I felt like he broke promises, like he never loved me, he was mean and I resented him for making things so hard for me. I asked him so many times if he was ready for marriage and he was so sure then he just snatched it all away so quickly. He however changed after we broke up and began to treat me very nicely. I had only been a week but I was shocked! One night I asked if he could give me a ride home from work and he said he didnt want to take me home that he wanted me to stay with him that night instead. We had and it felt almost like the beginning. Until he told me that I was wonderful its just that he is not ready for the commitment he was offering. We used to argue alot but the was always great, I asked if a ual relationship was something that we could continue. He never responded. I was furious and upset and lashed out I called him maybe like 20 times, left crazy voivemails and texts. I was embared at my reaction. He called me the next morning and said that he didn't have his phone thats why he didnt answer and would appreciate if I never spoke to him ever again in life. I feel like I screwed up big time but I guess its only been a week so mixing that with and my feelings of abandonment I just lashed out at him emotionally. He told me I was crazy and he no longer likes the person that I am therefore that was the last time he will ever call me. All this time he apologized for how he treated me in the relationship saying that he neglected me but now the tables have turned and I feel like I messed up big time. Maybe it was too soon for the and it made me rehash negative feelings about our split. IDK, what do you guys think? Did I really ruin any chance of a friendship or reconcilliation? Am I now forever labeled the crazy ex-fiance/girlfriend? Your thoughts please...
