So last night, he admitted he was going a bit stir crazy and asked if I minded him popping off to the pub for the evening (we have an 11mo DS so couldn't both go). I said I didn't mind, so off he went.
Later on, he called to say he was off to see a random band and would be back 'before midnight, definitely'. I took that with a grain of salt but was glad he'd kept me in the loop.
He eventually stumbled in at around half-past midnight, stumping around making lots of noise and generally being a nuisance. This woke DS up and I had a fun half-hour trying to soothe him back down. Thus began an unpleasant night where I eventually had to move downstairs and sleep on the uncomfortable sofa because DH's flailing arms/legs, v.v.v.loud snoring and random loud whimpering noises (plus duvet theft) all made it impossible to sleep in the same room. I'm 32+5 with PGP, so was not impressed frankly. It didn't help that he snored so loudly that it woke me up downstairs!!
He came downstairs at around 5am when he'd sobered up enough realised I wasn't there and insisted on sleeping on the sofa with me, all the while trying to tell me that 'he could have been a lot worse' 
Mercifully DS permitted a lie-in until 7.45 so I did get a bit more sleep.
I now seem to have been stuck with the morning's allotment of childcare while DH sleeps it off on the sofa.... to be fair he has admitted his behaviour wasn't great but he is one of those people who can't be penitent for very long - he will apologise and then come up with loads of reasons why his behaviour wasn't that bad really. I have to keep reminding him that all my previous transgressions (2 years ago?!) don't excuse his current ones!!
So right now DH has gone back to bed, DS is napping (thank you thank you powers that be) and I'm sitting here trying to NOT be in a bad mood for the whole day.
What do you think? AIBU to be annoyed with him?
