Why don't you stay put and you look for a lodger? A nice quiet female who could be a positive influence on your D. Make H be the one to move - if he has the balls. Next time he starts a convo like that try and tell him you are going to place an advert; even if nothing comes of it, getting some responses/ applicants might just put the wind up him and it may well offer you the back up plan you need.
