Should I leave him? Or not

Violet

So my boyfriend and I got genital herpes idk whose fault was it but I think it’s his fault. I’m not in love with him anymore and he disrespects me all the time. And makes me feel like shit. He says if I leave him he will kill himself and thats true because he tried once. It’s hell being with him. I feel trapped. But my thing is no one later on will want to be with me because I got herpes. What should I do?
