Need some really good advice 😅

Okay so me and this guy have been on and off for a year now. No matter what happens between us we always end up back together. But we still break up after a few months. It’s a cycle that we can’t seem to break. We’ve been through A LOT together. And when we’re doing good and don’t have any problems in our way I start having doubts about the way he treats me. I’ve ended things with him because of my doubts before. But once again, we’re back together. It seems like we’re always on and off and I don’t know how to stop it.

Like in the past we’ve broken up because of lying and cheating and also smaller issues. My doubts are always things like I have to ask him to do things instead of him just doing it. And even when I ask him he gives me a hard time. He jokes too much. The other day. Asked if he could carry my bag for me because it was heavy and he told me no, after fighting/teasing with me about it he finally carried it for me. It’s not all superficial things like that. But that’s how it goes.

So best advice everyone has? Is it possible to stop having doubts? And if we do break up is it possible to stay broken up? I’ve tried blocking him on everything, finding a new person to be with, focusing on myself. All of it
