Not sure if I am just being oversensitive.
Been married to DH over 20 years and over that time we have had a few wedding invitations from his work colleagues etc. I always attended willingly even though I wouldn't know people. So last week I received an invitation from someone only I see socially. He is saying he doesn't want to go and reeled off a list of reasons like cost, etc etc. Never an issue when it was people he knew.
WIBU to go with a friend if he refuses.
