Sorry you've been through this!!

When making your exit, I agree, do it in the most stealth way, possible, your safety is in dire jeopardy at the moment of leaving.

Make sure you have the basic essential, your license, passport, cash, birth records, etc, in a safe place. And a bank account(if you are allowed to even have one).

I hear your concerns about going into the arms of a man who is treating you nice.
Maybe, he'll support some therapy work, while you are together. To give you time to recover. If he's a nice guy, I'm sure it will be ok.

Hang in there.

Please keep us posted, that your extraction was a success!!
