I agree w/Wonka...go as dark as you can and make an appointment w/a lawyer asap. Protect yourself, your children, your financials and assets. Don't believe a word he says about taking care of you and/or your children. You want everything in writing and done legally.

I'm very sorry that that it has come to this.

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.
