I initially would have said maybe, given the details in your OP. But later posts from you and I've changed my mind, absolutely no way.
He's "selfish", DC don't want to see him much for some reason, he's happy freeloading off people and you think he'd be very comfortable being a cocklodger. Nope, nope, nope.
For context, my DP has always worked but never found his niche. He is a lazy arse intrinsically - he doesn't like working, but I suspect that's partly because he's never found a job that he really enjoys. It's always been a slog and he's been unlucky with redundancies (always got brill reviews/pay rises but companies got bought out and the whole office made redundant. Three times).
My DP has always worked. Paid his way. But now he's off sick - a condition which has been rumbling away in the background but never diagnosed has flared up with a vengeance and it's now looking as if he can't go back to his old job. But we don't know what else he could do.
Thing is, we have two disabled DC, one with particularly high needs. I enjoy working and I'm self-employed. When he doesn't work, he's so much more supportive and engaged and he is great with the DC. When he's working F/T, he's tired, grumpy and reluctant to pull his weight.
This life is too short to be miserable. Me and DP are having serious conversations about whether he can go back to work, and if not, what life would look like. Due to DC we don't have holidays or trips, and lead a pretty quiet life. We're just moving and having a big life change which will slash our outgoings. So maybe he won't return to work. I don't know. But I don't judge DP for it, and selfishly, I quite like the idea as he's lovely to be around when he's not working.
Your situation sounds very different. My DP is very grateful that I'm even willing to consider it as an option and is worried about putting pressure on me to earn. It's a joint decision that we'll take and if we go ahead, he will be responsible for taking on lots of the stuff I normally do. Because we are a team. That doesn't sound like the kind of situation you'd be getting into and if you've got the ick already, I think I'd be setting this one free - no matter how charming and gorgeous he is.
