Scooby, I would venture to say that he's been served, i.e., from your postings on another forum. Right now, he's remaining silent because he knows that if he does so, it will create a lot of anxiety and worry in you. Don't let him see you sweat!
I would suggest that if you are that concerned about your welfare that you and the kids go stay w/someone for the weekend. I'm sure you have friends that would be more than willing to have you stay w/them. There's nothing more we can suggest other than go somewhere else or have someone come there. He's not going to leave and he's going to make you miserable the entire weekend and I, for one, say that you need to think of your own safety now because it's too late if he should do you physical harm.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
