NC for this sorry, as I don't want it linking with my other posts...
So basically, DH stopped drinking alcohol some 2 and a half years ago, and whilst I know it's commendable for anyone to give up booze, I now find evenings out with him somewhat intolerable. We have been out together, with various friends and colleagues to a works party, or a random 'do,' (usually between 7 and 12 people,) around 15 times in the last 2 and a half years since he gave up booze.
So, 2-3 hours into the evening, (and by 9 to 9.30pm, and half a bottle of wine later,) I am really enjoying the night, and wanting to chat and giggle and dance til way past midnight. But DH wants to go home because he is 'bored' or tired or 'doesn't feel well.' He used to love staying out til the wee, small hours when he drank, and we had a great night together, (and with our friends,) and would get a taxi back together (and also one there...)
I am pissed off with now leaving 3 to 4 hours before everyone else. I can't stay on my own, because he won't go without me. On the occasions I have said 'I am not ready yet as it's only 9pm, and the night is just getting going,' he says 'I will wait then,' but just sits there, refusing to dance, refusing to speak much, and looking at his diet coke on the table, looking at his watch, and yawning. So I can't enjoy it anyway, and end up just giving in, and leaving with him. 
I am not saying he is boring in general, and I have no issue with him being a teetotal, and 95% of the time it's fine, as I don't drink anyway (unless we go out for a night with friends...) But he is an insufferable bore on our nights out, and it's ruining my night - almost every time. Even when me and HE go out together alone, just us 2; he still wants to leave at 9pm ish, and I am sick of it.
AIBU to be really pissed off and annoyed and say I am not going to ANY evening do again, with him there? I think I would rather just go out alone, (with my friends only,) as at least I won't have him huffing and puffing and saying he is bored, and wanting to leave at 9pm.
We are both 40-ish , and have no school age kids, so no huge reason for DH to be tired and want to leave early. And as I said, before he stopped drinking alcohol, he always wanted to stay out for the whole night.
