Your still trying to hold onto that house. If your parents can help you buy that one, they can help you buy a different one. If your husband won't be reasonable about moving out when your parents want to buy the house - you need to fight for it. You can't just wait. Clearly you cannot just wait him out.

Personally, I would get out of the house if you can do that with taking the kids. Get out. That house has his stink of memories all over it. That house will reek of failure for a long time. That is what happens during the first divorce, especially when Religion is involved. You feel like you failed at some life responsibility and it messes you up. That is all over the house. Every room, every furniture. Memories of things you will want to try to forget.
