Teenage DS has a long term GF. She is v controlling (he can’t see this yet). He wants her included in every family activity which where we can, we accommodate. However whenever there is an extended family event he also wants her to come along even though she has not been invited, is not liked and is not family. This puts me in a tricky situation - should I call the extended family member and ask that she be included at their expense - or ask him to do that himself - or tell him it is rude to ask if someone has clearly not been invited?
