@RevolvingPivot Honestly an invitation to a wedding or big party makes my heart sink. I make the effort to go to most of them because DH wants to and considers it nice for us to have time out together as a couple (we have small children so we don't get out a lot).
But I have got a lot more choosy. If it's something that I really don't want to go to now I say no and DH goes on his own.
As for doing couple things with DH I am totally not opposed to that. We had a tough time a while back (pre-diagnosis) because he would try to organise 'nice' things for us to do and I just wouldn't want to and he took that to mean that I didn't want to spend adult time with him. Now we know and our understanding is better he realises that actually a night away in a city with a bunch of friends where we go for a meal, drinks and then to a bar, or even just the two of us but something where we need to get a busy train, then go to a loud and crowded venue (like a concert or comedy show) and a packed train home again is not something I consider a nice time.
A night where the two of us go away to a hotel, have a lovely meal, have a wander around wherever we're staying and maybe go for some quiet drinks, lovely. An evening at the local small theatre that we can easily drive to and from and watch a comedy show, great.
I also now plan more, if we have any 'event' coming I try to make sure I have time either side to prepare and recover. Doesn't always happen, but we try.
