So I'll start off by saying that I have never and would never cheat on my boyfriend, so in a way this whole thing is pointlessly hypothetical, but it's still been bothering me. We've been together for over a year and are both in our early twenties. He's always had trust issues, mainly due to low self-esteem which wasn't helped when his last (long term) girlfriend left him for someone else.

So basically the other day he told me that if I cheated on him he'd revenge-cheat on me. He's mentioned this before but it was a lot earlier in our relationship so I kinda figured the more he grew to care about me the less this would be an issue. Apparently not. I'm hurt that he's the kind of person who would want to hurt me, even if I hurt him. If he cheated on me, I'd be distraught, but I'd never do anything to hurt him because I love him. I kinda feel it should be the same for him. I'm also hurt that he even considers the possibility that I'd cheat on him, because I never would.

Just a bit of background regarding our relationship, I'm not sure how relevant it is. When I first started going out with him I was already in love with someone else, unreciprocated, and I'd never made any attempt to be with this person either before or during my relationship with my boyfriend, so it was merely an internal struggle of mine. He found out about this and was extremely hurt that I hadn't told him about this when we first got together. We hadn't even said the L word to each other at this point. This, I think, has made him trust me less than he otherwise would.

So reddit, WIBTA for getting upset at my boyfriend's plan to revenge cheat on me if I ever cheated on him?
