I'm really sorry your going through all this, especially the fact that it was your husband who turned you in.
By what you shared so far seems they have no idea what to do with such a strong woman...lol.
Trust me, they are trying to figure out how to put you in your place and yes they will use anything and anyone to do it.
My advice would be not to meet with them...refuse any communication and just let them do what they're going to do. The only control they have is what you give them.
I wish you and your kids all the best.
