Done with his ass

So I'm fighting with my bf of a little over a year and a half for the millionth time this month and we've had a pretty hard time this past few months and I think I'm done. The only thing I'm afraid of is that I've sent him nudes. And he has them. We both made a deal that we would delete each other nudes and not show anyone if we break up but we all know how some guys are. What do I do?
