break up?

My boyfriend and I are having issues with our relationship. He tells me I basically blame him for everything which I don't recall but I apologized anyway jusy to avoid any arguements. He talks to another girl every single day and basically admitted that he likes talking to her. He thinks it isn't fair I have a problem with this and tell him off for this. It's like I look forward to seeing him hit don't because that always flashes in my head. Am I even wrong and should I end this?
