Ainu?
Firstly I'd like to say I didn't go to bed until 11.30 pm so dh could get a few more hours sleep and get settled as he's just done a 14 hr day and is up again at 3 am so I'm probably just tired but think my anxiety is going to hit the roof pretty soon 
So to the Aibu bit.
Adult (20.5)ds is moving into a house with friends this weekend.
He's my eldest and first born and I have younger dc but I'm getting more worried about it as the week goes on at the moment.
As much as I love him he's so lazy and messy at home. He works late shifts.
His gf stays over with him 3 nights a week which was our compromise as it was every night at one point 
Anyway things like general dishes in sink and not dishwasher,towels in his room and not hung out,mess wherever he goes generally.
So tonight he got home from work at 10ish with gf in tow and they went off to a friends for a few drinks. Fine
Asked them that when they get back can they pls be quiet as dh has to be up for work early and so do I.
So they were back by 12 pm and I wasn't fully asleep (anxiety I think)I've got tv on in my room so I can't hear them and have given up and come downstairs to get a drink.
lol and behold a towel chucked over the kitchen door,most of the knives from my block in the sink along with other dishes (not in dishwasher)and they've left my front door unlocked
( a drop handle door not a take lock so has to be locked from inside or anyone could walk in).
I've just come and sat in front door step because I'm raging but also feel bad that i will feel slightly relieved after the weekend that once I've locked up and tidied up it will actually stay like it and I won't have to be tidying up after a bloody young adult like a slave.
I have this constant inner feeling of having the piss taken as I do quite a bit of helping with organising in general as he's useless at it.
Like for instance he hasn't got any boxes for moving yet and has a busy weekend already.
Me and dh will be helping to take stuff to the new place but be told him it needs to be packed and sorted before Sunday.
Am I being unreasonable to want him to start taking some responsibility and stop treating me and our home like a fucking hotel with built in maid service???
