Boyfriend Problems


So I've been with bf for 4 months but I've known him for almost 2 years. He's never trusted me by the way we met, but once we got together I was only with him. 2 weeks ago he got my phone and went through it to see if I was cheating and didn't find anything. He always thought that when I left the house I was going to meet up with a guy and things. I let him think what he wanted. We got into a cupple of fights on the cheating topic. I wanted to check his phone but I didn't. A cupple of days ago I got his phone and he was messaging other girls and sending them pictures. He was also talking to a girl he used to mess around with, and says that they're just friends now. I want too be with him and don't know If to stay and If he will keep on doing these things. πŸ˜ΆπŸ˜•
