My relationship is ruining my health and mental stabilty

My boyfriend is so dramatic , over protective , jealous from probably everything , he changes every situation into a useless shallow conversation like asking about boys , talking about how I dress , being mad that I didn’t reply fast . When I tell him his flaws he keeps whining about “always being wrong” , why I always just see his flaws , why everybody doesn’t appreciate what he does . Sometimes he keeps screaming and shouting madly that I start crying and not knowing what to say to calm him down . I feel like he just gives me negative energy all the time he doesn’t enjoy the moment he must find something bad to ruin the whole thing . I am a person who likes positivity and always willing to be better and not to make problems but being with him is making it so difficult. But despite all of that I really deeply love him and I gave him a lot of chances and I want to give him more because he has other good things too . I’m wondering shall I step back and stop this relation or shall I keep trying ? By the way after every fight he keeps saying that he’s sorry and that he knows he’s wrong and I’ll try to change i love you don’t leave me and stuff like that ..
