Like, seriously, I have had a few people talk about how my fiancé wasn’t conventionally attractive, but he’s attractive to me :)
Plus, he’s good to me, and I don’t date for looks. I’ve had conventionally attractive exes too who have been horrible people, so…
I can’t imagine caring that a happy family member or friend’s partner is less conventionally attractive, much less saying that to them!
You need to meet and surround yourself with less horrible people.
