Hi. I'm in no shape to be offering advice to you right now, but I do understand the problem with finding an apt. that isn't a dump but accepts cats. I'm in the same boat. It's awful.
I don't know what to say to you; your H. says so many sweet things to you; mine hasn't done that in such a long time. I still see a lot of hope for your marriage, esp. when compared to mine. Maybe selling the house IS a good thing. Try to think of it as a positive, maybe. Like you said, it could be a fresh start.
I am thinking of you. Hope
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
