I’m so depressed

Me and my dude haven’t been in a good place lately. He cheated on me back in March/April with some girl the girl facebooked me and snitched. My dumb ass stayed. He cheated on me again in may sometime. Different girl and the sex was raw. She was claiming to be pregnant but finally revealed that she wasn’t. Still I stayed. Now I don’t trust him. I go through his phone every chance I get and I always find something. I’m so sick of this y’all but Everytime I tell myself I’m done I fail at actually being done. I want to be done so bad because I don’t deserve this. He don’t got a car so he uses mine. I got a screenshot from a fake page of him texting a girl saying he wants to pull up on her. My heart is in pieces. You are actually stopping that low. Going to see another chick in MY CAR. How can I move on. I love this man to pieces but I don’t want to keep going through this
