He's been living back at home since leaving uni and has a good FT job and lots of friends he's known since school. He split up with his GF last summer - they'd been together 18 months but she lived with her parents near London and never wanted to move. They used to bicker a lot, and I don't know if that's still affecting him, but...
He's a bloody miserable sod. Flies off the handle if we try and talk to him, virtually every other word is the f word. Normal day to day life is very stressful for all if us because he doesn't appear to like us at all.
I know he wants to move to another city where some of his friends live, and is looking for a job there in the same sector he's in now (sports hospitality).
I don't want to force him to move out but there's only so much of his abusive, rude, angry behaviour we can cope with. It's depressing both me and DH and his younger brother too.
He won't look for a flatshare or anything round here because he wants to move to this other city. He does pay us a nominal rent, probably about half or less than he'd have to pay to rent a room.
Ideally we'd like him to stay living here until he can move cities, acting like a 23 year old young professional, being polite and happy, and not putting us through this angst every few days.
Any suggestions?
