My daughter and I have received a Christmas party invite from the family of her school friend. I have met the mother just once so I barely know her. I know that my partner (not my daughter's father) would love to come too. I haven't mentioned the party to him yet. I asked my daughter if I should ask the mother if he can come too but she thinks it's her old school crowd and their parents and he wouldn't know anyone so it'd be odd. It's true he has not met anyone who will be there but I'm concerned he'll be hurt as he always takes me to everything he's invited to. Is it rude to ask if my partner can come? Would I put the mother in an awkward position by having to refuse my request? Is it acceptable to ask? Thank you.
