I posted about this a while back in AIBU but am in need of advice again 
. A family member (I'll call her FFM, Female Family Member!) of DH's was putting pressure on him to go to their fiancé's stag do, in particular because 'they went to DH's stag'. We aren't in a position to spend hundreds of pounds on it when the fiancé isn't particularly close to DH. It's also Christmas and the stag do is in the spring so we will be skint.
When it first came to light about the cost, DH was in complete agreement with me that we can't afford it (he has no spare money at ALL after bills, utilities, living plus Christmas gifts, and we are trying desperately to save). We both winced at the crazy £250 price tag of the one weekend, so came to a mutual compromise that DH would go to one of the days/nights of the stag and then come home. Stag said this was fine - All happy. Just a note - I'm also going to FFM's hen do which will be ££s, and their wedding is far away, it will cost about £400 for us to attend.
At regular intervals, say every few months, FFM will text DH and start bullying him into going again, at first it was 'oh we'll pay for you to go, you can pay me back'... Um, no thank you. And this morning the messaging has started again, this time because 'someone has dropped out and we need you to come to the activities after all'. (it's not even FFM's event!)
Instead of rolling his eyes and replying with 'sorry, our decision has been made', DH is now giving me grief about it and seems to want to go. I said I am upset and tired of the bullying from FFM, and that I thought we had already come to a compromise and didn't understand why it was being brought up again. He said "Ok, great discussion" so I replied, "I thought we'd already had the discussion, why is this continuously coming up?"
He just replied saying "Forget it."
I'm pretty sure he will have said that I said no to him going. To cut a long story short, I feel like a bunny boiler killjoy that just doesn't want him to go, even though we decided together as a sensible, joint decision. I feel like this will always be an issue, him deciding to disregard me completely rather than upset a family member. This has happened in other situations since we have been together too. We've only been married a short while and I really don't feel like we are a team in things like this.
Sorry this was so long, upset ramblings
