I took DH's name when we married. I have never liked my father's family name, nor his family (long story). I refer to myself as Mrs or Ms, I'm not really that consistent.
Here is the issue (that frankly is making my BLOOD BOIL): DH has an uncle who insists on addressing Christmas cards and invites to Mr and Mrs "DH's initial" Surname. He knows I don't want him to as MIL (it's her brother) mentioned it to him. However, he still does it and treats it like a joke. I should mention also (for context, you understand) that he is a pretty horrible person: racist, homophobic, arrogant and once took the piss out of my DS (5 at the time) for having nail polish on his toes!
This man is a shit, right? I'm right to be fucking angry, right? What to do though?
