It's not very nice of them to gang up on you like that

Not including you in any activities and then basically making fun of you is pretty crappy, I'm sorry

Anyway, I'd love to see you get a Yorkie but would be afraid that your husband would demand that you get rid of it, so it would be best to have his blessing first. Is he soft-hearted at all, such as with children or friend's animals? If so, you might get away with the "ask forgiveness" thing, but if not, it could be awful for you and the dog if he wants it out of "his" house.
Good luck with this, I really hope that you can get a baby to love! I don't know what I'd do without my little girls, they are my constant companions
