I have to agree with you. Since it was obvious she was pretty much ignoring you (case in point: the people coming to look at item for sale, and she waves you off to take care of it) obviously she was quite interested in the conversation she was having with this guy. She SHOULD have said that "This is my husband "Joe" (or whomever so he had a good idea who you were!!! And you're right -- she would have been REALLY upset if you hadn't mentioned she was your wife, if you were talking to some pretty, curvy woman !! So yes, she was being rude and you were not 'needlessly bothered.'

Sounds to me like you two need some marriage counseling. Might be a good idea before this marriage falls apart! Give it a try. You won't regret it. God bless and take care. Hugs, Lee
