No way would I settle with this man. You think he will settle for "settle"? Nope, he will keep right on going.
"Father's rights" are one thing (don't get me started on what I think of those organizations) but this guy has "bad parent" written all over him.
I don't think the court will change a thing until the judge hears from the GAL. Nothing he is alleging makes this an emergency. All this is really stuff for the final hearing, not an order to show cause.
You really SHOULD have a lawyer on your side, though. Have you checked with the local DV office, Legal Services, etc., to see whether there are any lawyers who can provide free or reduced-fee representation? Maybe your local Bar Association?
