sue, sorry thigs are sounding down, but know that things change, no separation is not the best way to work on a marriage but sometimes separation leads to people working on themselves and then realizing how much they really value the marriage.
my h moved out, against my wishes, when he did I said it wouldn't help us it would be the end of us. started to look that way for a while and he even asked for a d and expressed that he had fallen in love with his "friend" now for some reason six months after walking out the door and saying it is over with us, he is wanting to try, has not moved back home yet but is working toward it. so don't look at separation as a marital death sentance. don't however mention it to him, if he wants to go then let him. sometimes it is what people need.
