One year, I - a woman no less 😇- forgot my first husband's birthday. We'd been travelling back into the country and I was tired and just forgot, I had remembered a day or two before but couldn't do much as we were travelling, but I would at least have wished him a happy birthday as soon as it rolled round and discussed plans for what he wanted to do when we got back, and I did have a card stashed in my backpack, but that pleasure was taken away from us both because he sat on it instead of just saying "Ahem, have you forgotten something?" or something similar.
Worse still, at the airport we had to sign something, can't remember what, and I actually asked him the date, which he gave me very dryly 😎- I was tired from travelling, which is not much of an excuse, but it was the truth.
When we got home from the airport a relative had left a message wishing him a happy birthday on the answering machine (this was a while ago when people still used such things) and I was horrified.
I felt really rotten, and I was never one for forgetting birthdays and usually made a big fuss, but the travelling just threw me. He didn't act out about it, but you could see he was pleased I felt a bit shit. It would have been a really kind thing if he'd just reminded me. To this day, years later, in a different place and with a different husband, I feel a tiny twinge of guilt at that memory.
I guess that's what OP was hoping for, for her husband. Point scoring from "loving" spouses is never a good sign.
