My bf lives at home, he's 37. We've been together on and off for 5 years. It's fine by me, he's 3 hours away, he comes here to visit, I've never met his parents and don't really have any wish to and he knows it.
Sure, I find it odd in that I could never do it and I'm not from a close family but he's had money/helth issues over the years and if I'm honest being a single parent (and I did not plan this) helped me get my own place, or keep it at least when ex left me so who knows where I'd be or if I'd be at home now.
It's a fairly casual thing, I mean I'm faithful as is he and we talk daily but we don't live in each other's pockets and don't want to, I'm happy to see him monthly, sometimes more, sometimes less and I have times I miss him and wish he was here, but mainly I'm fine on my own.
I'm also stubborn, selfish, need to be in charge and would be a nightmare to live with, so not only would he have to move from all his friends and family to this town, which co-coincidently I'd leave like a shot as I hate it, he'd have to get his own place here and even I wouldn't expect that.
It depends what you want from the relationship really, and I'm happy with mine how it is. I'm somewhere between single and not, erm unclassified? I dunno, I don't label it really
He's not a Mummy's boy though, no way, he's totaly independent, just shares a home with his parents though he is a geek but then I watch soaps and read gossip columns.
