My husband isn't terrified of my snakes, but he won't hold them or anything. I don't breed, but I've got a pretty large collection considering the size apartment we have. IMO it shouldn't matter whether or not the other person likes snakes; it's what you want to do. As long as their fear isn't so bad that they're going to have constant panic attacks just being in the same house and you're not spending so much you cause financial issues, there's no reason it can't work out just as well as someone having a painting studio or music room.
