Do you ask your DP to stay downstairs when he comes in drunk? Do you sleep downstairs?
Every bloody time DP comes in he tries to come upstairs even after I asked told him not too.
I hate the smell of stale alcohol on the sheets, DD is still co-sleeping at 13 months (we do have a super king and she's on my side so not really an issue)
He comes in last night at 1am and I can hear him creeping upstairs. Stumbles over the doorstep and starts getting unchanged. I told him to go downstairs. He starts moaning its cold down there and he's going straight to sleep. DD wakes up 
. I manage to fall back asleep and then he's moving around in the bed because he can't get comfortable. I told him to fuck off downstairs. He starts telling me about his night because he's pissed and isn't listening. I told him to shut up and go to sleep. Twenty minutes later I wake up to him throwing up out of the window . Woke up properly this time and told him to go back downstairs and that he isn't sleeping up there with us if he's that pissed that he's being sick. He ends up ranting about 'not being able to sleep in his own his in his own house', 'work all week and can't even sleep in his own bed'. Basically just being a twat because he's drunk.
This happens every bloody time he goes out. I don't think its unreasonable to expect him to stay downstairs when he's pissed.
AIBU?
