I’m not happy but I won’t leave

This might be a long post. But I really do need the help.

I’ve been with guy for over two months and there was once or twice we broke up. Over something pretty serious that he did. We got back, trying to make it work because I do care about him. He seems to care about me. But I’m not happy. I know I’m not but I don’t wanna leave the relationship. I don’t want nobody else to have him. Like I dont enjoy myself driving around, we fight ALL the time. Like so much and always on the verge of breaking up. We are the same way tho in a relationship. We both want the same thing. But I’m not happy and I haven’t been for a couple weeks now. Yet I don’t want anyone to have him.

I lose my mind if he checks out girls, i won’t even go into stores cause I’m worried there might be a hot girl or he’ll look. Like anxiety to the rooooof. It’s become such an issue I’m always stressed. I get mad even if he looks over at a vehicle cause what if it’s a girl, and he looks multiple times. I don’t know what’s wrong with me. I need mental help. I want him to myself but I’m not genuinely happy. What does this mean like... there’s even problems in it to. Like him not working out any problems with me. I’m drained but I want him 🥺😖
