I was reading Dear Abby this morning, and the last post was from a woman who has been with a man for 10 years, yet when he is invited to a wedding, there is never "and guest" or her name on it. He then calls up the host and says if she is not invited, he won't attend. She feels this is incredibly rude and makes her uncomfortable. Abby agreed, saying he was "blackmailing" the hosts and they would sometimes say "sorry, we'll miss you" instead of allowing him to bring her.
I'm sorry, but I totally agree with the husband! I'd be pissed if FI was getting wedding invites that didn't include me, and then went to the wedding, telling me I wasn't invited.
Anyways, I thought you ladies might want to read this.
