GF keeps trying to goad me into hate fucking her

We have been dating for several years now. We live together too. We have for the most part a really good relationship shes really attractive and we both get on well.

We used to pride ourselves on never having fights like other people we know in relationships heck when we first got together we even promised each other we would never fight. But i think that got forgotten about after a while.

We had a pretty big fight where we both weren't talking to each other for 2 days as we both felt we were the one owed the apology and not the other ( it started over decorations but became more about lack of respect and what was said etc. ) I don't really want to get into the details here but she definitely was in the wrong on this one and i didn't want to back down so yea it carried on for a while.

Somehow this turned into us having sex while still not talking and i was still mad at her. So i was kinda taking it out on her a bit with the sex. being rough holding her hair and fucking her face etc.

we made up after this and forgot about the whole thing.

But heres the issue its taken me nearly a year to figure this out but since then we have been fighting all the time and its always stuff she starts and it always turns into sex at the end.

I think she is doing it on purpose, I wouldn't mind it as the sex is really hot but ive not realised that she must have broken my computer on purpose and really hoping not the case but she scratched my car and now im paranoid that its all because she wants angry sex...

I accused her of this and we fought over that instead and i just can't seem to find a way to solve this

I am seriously considering breaking up with her but at the same time we have been together a long time and sorry if this is shallow but she is really cute and im not sure ill be able to find another girl that cute.
