I agree with what has been said so far about not forcing her. Also, mentally accept the fact that she may NEVER like snakes. Maybe this won't be an obstacle in your relationship, maybe it means she's not the person for you. Either she will see how much time you spend with your snakes and decide to share you with your pets, or she will get upset and pull the "it's them or me" thing, or perhaps you can all live in peace and keep the two worlds separate. Who knows, but that's what I see.
