DH and myself have invited a close male friend of a very very long time to become Godparent to our DC. Friend accepted. Friend who is in his 20s has since started seeing a girlfriend who is in her teens and has become pregnant and they are starting a life together. The problem is, this girl is AWFUL. It's my belief he's with her out of duty rather than love, but they're talking about marriage! She happily drinks and smokes even though she's pregnant, swears loudly in public, is a terrible liar (and a CHAV! EEK!) and has even gone to see ex boyfriends and have them over without my friend around. There's no way I want this girl around my child when she's barely more than a child herself. She picks silly arguments and TBH have not really got to know her and I don't want to.
AIBU to either not invite her to be Godmother at all, or ask my friend to step down? What's the done thing here, am I expected to ask her to be Godmother seeing as her boyfriend had already accepted Godfather?
