Name changed in case I'm identified from this!!
So this evening DP and I both went for drinks with separate friendship groups. He got there about 8:15 and somehow ended up at a house party with colleagues who are all several years younger than him. He knows he has to go to a friends wedding and drive there tomorrow, so said he would only drink a couple. At 11pm he phones me in a complete state saying he's done loads of shots, drank several beers etc. He only just makes the train home because it's late, gets home at midnight, eats half a pizza and vomits. I then find him passed out in bed.
If this was once in a blue moon, I'd say no more about it. But he gets carried away and into a state so that he misses trains or is too hungover to do stuff every time he goes out with work people. I find it very frustrating especially when he's said he's not going to drink too much that he always gets really drunk.
I am not going to the wedding tomorrow. He's passed out and left all his stuff downstairs so not got an alarm. AIBU to just let him sleep, and if he is late to the wedding, let him deal with consequences?!
