Oh hooli, I have so much to say but I don't want to make this difficult time more difficult.
He's being spiteful towards you by trying to force you to seel the house. That in turn hurts the children you claim he loves so much. You need a lawyer. Add costs of trial to the list of things he will be responsible for paying. It's time to be not so nice. I know you're grieving and in pain emotionally. That this seems surreal. It's very real. If I could reach I would hug you and help you. Why is Australia so far away? It's time to get angry and let mama bear out. Much love!
