X demands full custody because I'm now engaged

[sleeper]

I met with counselor X has taken kids to last night. I didn't know where to start so I began with day after engagement when X informed me she had talked to a lawyer and would be "taking full custody of the children", kids confusion, DS asking what "if mom had a gun...", X freaking out trying to twist his words around, questioning him to the point of tears, having him phone me and telling him what to say (clearly heard in the background) and finally taking kids to counseling (without informing me of TWO appointments).

Counselor basically tells me she can't talk to me about my children or be my therapist because she has already begun working with my children in the context of another "family".

Just had a call from X. Big spew. She wants to come in my house to get things she left her TWO years ago. I told her I done feel comfortae allowing someone in my home who is suing me but I would get any items of sentimental value her (I've already requested a list). She went ballistic. She then asked if I would tell her if I take the kids out of town. I responded if I take them out of state as per custody agreement. She went ballistic again.

Now threatening taking full custody, child support and says I will be served tomorrow.

And she doesn't understand why I don't want her in my home.
