Hi 3boyzmom, I am right in this sitch too only my H is still at home. I ask many of these same questions every day too. I almost asked my H to leave the other day, but realized it came from pure emotion and probably would not be handled well. So I"m not sure I have any great advice on this as I am in the same spot and still struggling with it as well.
I have read over on the Mid-Life Crisis forum often as there are some women in the same situations as us. It helped me to read their posts and the responses people gave them. Their post names are Tina825, LoisB and wishing, hoping. Maybe that will help you some, until some wiser vet here can post some advice.
