Abusive relationship recovery!

Hello ladies!

So I was in an abusive relationship for a year and a few weeks ago he left me for another girl and I've actually been doing okay and healing and realizing that I am worth so much more than he made me feel like I was. The abuse was never really physical though I was scared many times that it would become physical. I am under 5 feet tall and very petite and he is 6'3" and very physically imposing. There were several times he would hold up just fist like he was going to punch me and would hold me down and scream in my face and call me a bitch and an idiot and stupid and crazy. He denies that any of that happened and leaves me feeling insane and questioning my own memory. I recently found out from a friend that he told people I punched him in the face when he broke up with me (never have done that never will do that) and told people I am psychotic and that I was awful to him and I feel terrible becsuee I worked my absolute hardest to be perfect for him and it was never enough. He was with another girl 2 days after he broke up with me which hurt a lot. She was my friend and they immediately started officially dating and I suspect something was going on while we were together. I have also been hearing other things about other girls he was talking to while we were dating. He says he never cheated on me and I always believed him but now I'm not so sure. We had good times but they were tainted with my anxiety about relationship and whether or not I was good enough. I have been reading a lot about narcissism and I truly think he has it. I have been doing okay and I'm moving back to Boston tomorrow for college and I'm moving on with my life but I still have self doubts and I question myself. I know it was for the best that we broke up. He is going to college this year and he probably would have cheated on me once we were apart. I am ready to move on and live my life to the fullest. Anyone have any tips on how I can move forward with myself and learn to trust myself and others again?
