Husband and I got married a couple months ago. Before this we'd been together 14 years. It was important to me to keep my surname for various reasons - we spoke about it and he was understanding and very clear that he didn't mind. I asked if he wanted to share my surname, and he didn't - no issues from me. Incase it matters, we don't have kids and don't plan to.
We got a wedding invitation from a family member of his, addressed to Mr & Mrs Husband Surname. No issue, but given their wedding stationery will likely be getting made up and to avoid any mixed messages, I asked if when he RSVPs for us could he text just to clarify my name so it can be right on seating plan, etc.
He said it's not a big deal and if I care that much I can text his family member myself. I replied that it mattered to me as it's my name, and he got really snarky about it, reiterating it wasn't a big deal and he wasn't doing it.
I welled up a bit as his reaction and the change in tone of our evening as it caught me by surprise, and to be honest I'm tired from a long day at work and this was just after getting in the door. He then flounced off and has closed the door over to the room he's gone off into.
We rarely argue, I can't remember the last time anything like this happened, but it's really hurt me. Not the invitation, but his attitude towards my name not mattering and being unwilling to do a small task to support something important to me. I could of course reply to the family member myself but I'm peeved that I've managed the name situation with my family as well as his immediate family, can he not help out with his wider family I don't really know to message?
Am I massively overthinking this?
