I don't know if he loves her then I don't have a problem with it. But if he's using her to cover something up then there's something wrong.
Orientations are confusing and it's better off without it and it's not like some straight people are really into their relationships, they sometimes do it just for sex and bragging rights. I'm not saying it's okay but social climbing isn't limited to gays. I feel bad for the girl though but if both people are hot I see why they continue on this ********. Status.
