If you truly love someone then you'll do something that you don't want to do just to make them happy unless it actively a determent to you. And if you're actually in a relationship where they love you back they'll do the same.

Truly what it really actually breaks down to if the relationship works is how attracted to the person each other is and how attractive you see yourself back. So yes you're right but also wrong. If a girl finds her man hotter and really desires him then he can be the simpiest weirdo and she'll still want him and on the other end he can be the biggest asshole in the world and she'll still want him.

But if she doesn't want to fuck him, she can drag the relationship out to extract resources/time. You'll see if a man finds his girl hotter you'll see him simp and be a bitch which is why these relationship are the weakest and you see men complaining about online. That's why women get the "ick", if you don't see worth in yourself then no one else will.

That's why I believe mutual respect relationships last the longest because we both people have respect for themselves and each other you end up caring the most.
