Sorry if this has been asked a million times!
DP has been invited to wedding of a school friend whom I have yet to meet (they live quite far away). We have been together 3.5 years. It is just DP named on invitation.
Would it be extremely rude for him to ask whether this invitation includes me? Don't want to put friends in an awkward position by asking or assume the wrong thing. Asking on DP's behalf!
