Shall I leave him after a year and 3 months together?

I love my man to death something horrid happened. I saw text messages that he wants to be with another chick in Newfoundland. I freggin went nuts at him I confronted him screeching in angry and betrayal. He slammed me hard against a wall. It hurt I slapped him across the face and told him to get the hell out of my face. Did he do so? NO! I told him I saw the text messages and I am done, he told me he has the LAST DECISION OF BREAKING UP. I WANT OUT OF THIS RELATIONSHIP. Hes unfaithful to me. He doesnt love me. He tells me Im dirty below, if there was a problem Womens Clinic would have told me cuz I have a cancer scare in my uterus so always have to go to get a pap and check ups on a regular basis. I told him to never talk to her again and I checked his phone hes talking to her wishing again he was with her. I am so hurt I cried for 5 hours and being emotional. I wish my bf would respect me and love me. He never cuddles with me, I sacrificed so much and moved 3 hours for him. I broke up my engagement because I thought he would be a better man I WAS WRONG. He turns out now after a YEAR AND 3 MONTHS OF WASTED TIME with this slob. I need help what shall I do?
