Everyone gave you excellent advice - even 2 weeks ago. But we had no way of knowing that your H would go dark on you. Seriously, no one has a crystal ball. I would have paid big bucks for one when I was in your shoes.
You are sweet. You are NOT a burden to any of us here. We want to help you. But you really have to act this time.
Just because you contact a lawyer does NOT mean you have to get a divorce. In truth, my divorce lawyer told me straight out that he didn't think I needed one at all. What I DID need was a financial agreement. That's it. You could go the rest of your life without a divorce. It took me forever to realize that getting the finances sorted and getting the D were 2 separate things. Eventually I CHOSE to get divorced. That was what I finally decided I needed for me. But you are not me. And you call the shots here. But you DO need protection from a moron who does not want to support you and his child.
Now, call back this time and make that appointment. And hurry. You might not get in by Thurs. You have to act NOW.
