My mom decided she wanted to add a former co-worker to the list yesterday (we'll call her Beth). Beth and my mom were good friends for many years and recently reconnected. We have the space so I said ok and gave mom an invite to give Beth. Beth has never been married and has no SO although we did give a plus one. Beth recently moved to our town (hence the reconnection) and won't know anyone at the wedding other than my mom. My mom suggested another former co-worker (we'll can Tammy) be her plus one as mom knows they are friends. It was only a suggestion and we don't really care who Beth brings. Anyways Beth says she can't bring Tammy unless we also invite Tammy's new fiance. Mom and Tammy aren't friends and Tammy isn't invited to the wedding - Beth is. Are we obligated to invite Tammy's fiance as we suggested her as Beth's plus one?
I'm confused and need coffee lol.
