Re: Am I overeacting?
What do you mean by "going off at him"? Did you get loud and cuss him out?
If that was the case, maybe his reaction was predictable.
Anyway, I would be offended, as a spouse, if:
a) there was no invitation to me, but wait a moment: could it be the case they didn't know he was married? or that you are automatically invited, even if your name is not directly mentioned - an invitation to the family?
b) if the other party (my spouse) had seen no big deal in it, and
c) especially if the other party had not attempted to correct it, either.
I agree with you, but maybe there was also another way for you to approach him on the issue.
