X demands full custody because I'm now engaged

[sleeper]

So, after Sunday night's inciden, X texted Tuesday AM that the kids had a therapy appointment at 5:00 and could she take them. This is the 2nd therapy appointment she has failed to inform me of but she tripped herself up and I called her on it. I think she doesn't want me around the counseling because she wants to manufacture an issue (i.e. evidence I'm neglectful for not participating or orchestrate a reason for her to have custody/influence the kids). I declined letting her take the kids and informed her I would take them.

All Hades broke loose. She called and began litany of "reasons" why she should have full custody which swirled from children's education to not wanting our children living with fiance's children to bits of pieces of obscure things from our past that I couldn't really connect to anything rational at all. She finally hung up on me. Then she texted I would be served soon, etc, etc. I calmly texted, "You have no grounds for full custody, there are plenty of lawyers that will be happy to take your money but you will accomplish nothing."

She showed at counseling session. I didn't participate but met counselor. She requested several times that she and I leave to talk more, go for coffee. Although she was calm I politely declined, explaining that I was tired of it. I have session today (alone) with the same counselor that I made for myself.

She texted first thing this AM requesting once again we get together and "talk". I declined again. She has now texted she wants into my house to get things she left there when she sold it to me 2 years ago (no written agreement about that). I told her yesterday to send me a list of what she wants.

I don't think we have much to "talk" about and I don't feel comfortable letting someone who says she is sueing me into my home.

It's as if she realizes she no longer has any control over me at all and is grasping at anything that might allow her influence in my actions.

Thoughts anyone?
