I feel weird about my two best friends wanting to hook up with each other.
what is so weird about it?
I don't know, I just feel a bit out of place with it
You're right you have gotten used to see your best friends just as friends. So now it must be weird to see them as a couple.
I don't think so, I think it might have something to do with the fact that they are both gay
Gay or straight, that would bother anyone. Also, what if they break up and don't want to be friends anymore? Your fears are reasonable.
