My thoughts have been as the majority on here, not to sell your own house.
What if Rufusmum's DH, sold his house, bought a boat, decided it wasn't his dream after all, and moved in with Rufusmum? If they then decided that living together was not compatible, could he be asked to leave? What if he decided not to?
All sorts of horrible thoughts come to mind.
Rufusmum, make sure you keep your own property, in your own name, and speak your mind . If the very thought of sharing a smallish house is making you feel depressed now, what will it be like, if it became reality?
As others have said, Don't Do It !!!
