I need someone to talk too

Hey all,

Me and my ex were very on and off for the past 6 months. A lot happened in our relationship that caused trust between us to fade. I personally couldn’t trust him at all anymore because he had left me 3 times. We had got back together in May and he ended things with me in July due to family problems which are now all of a sudden gone ...? And he left to LA to pursue his fighting career. While he was there we rekindled our relationship. He messaged me telling me that he would never find someone like me and all the cute things a guy will say to win one back. I told him that he had hurt me so much and I needed to do a lot of healing. He proceeds to say that he will be there for me. At this point the trust for me is gone. And tbh my self esteem is hit as well because he left me but would talk to other girls to try to move on from me. Anyways I know his social media passwords and I told him I didn’t know. Sooo I logged in to have peace of mind that I wasn’t being cheated on and wasn’t making a mistake. I know it’s crazy. Anyways he had mentioned to me that he doesn’t want me doing that. And lied and said I would stop. Any ways he recently found out and left again. And now he’s following a bunch of whores on social media. Oh and he had asked me to move to LA with him. I live in Toronto currently. How can one move on so quickly ??? I know what I did was wrong but shit I’m so hurt. Every morning and night I have complete breakdowns. I drive by places we had dates at and cry. I don’t know what to do. His mom messaged me asking about him. I’m just so hurt and confused.
