I don't think the GAL is necessarily on your H's side. I think the best interest of your kids is being considered. Your current situation just isn't working and it seems to be escalating. I'm sorry about the insensitive viewpoint of the GAL regarding OP in these situations.
Why can't your attorney get a temporary support order ASAP. It's unreasonable to expect you to move without immediate financial support. If that's not possible, do you have a case for moving back home? You and your children need a place to live. I can't imagine any court telling you to leave without a home and money.
It may seem like your h is gaining traction, but he isn't. In fact, he now may be forced to quickly refi (which you've said he can't do) or agree to a sale. His delusional plans may start to unravel.
