No, I don't think Christmas and your FB page have anything to do w/this. I think his attorney has gotten in touch w/him and has advised him that he's in hot water over the child support, etc.
Just remember, your lawyer is there to protect you and help you get what you need. I don't like the idea of him wanting to sit down w/you at this late date to try to negotiate a settlement. It makes me very uneasy. But you have to be the one to decide what you want to do...but always keep in mind, they don't play fair and when it comes to money and their freedom, they'll do anything or say anything to get what they want. Look at wishing,hoping is going through. If your gut says don't do it, then don't. Your gut will never lie to you.
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.
