She must be seeing a lawyer...what now?

[Awoken]

WAW called several times today, while she knows I'm with the kids. I can't help but think she is knowingly trying to disrupt our time together, but maybe I'm just reacting and mind reading.

I didn't answer, waited for about an hour then sent her a text saying, "hi, what's up?" , she replied "I want to talk about the Seattle trip". I replied "I would like to talk about it in person on Monday when we agreed." She'll be back in town very late sunday night. She responds "So, you want to hurt MY family with this!". I replied, "I have no intention of hurting your family. We agreed yesterday that I had 2-3 days, and it's only been 24 hours. We can talk Sunday night if you want, but I was aware that you will be getting in very late. Just let me know if you prefer Sun or Mon.".
30 minutes pass, and then I get her reply of "Fine."

I dunno, but I think it was good I didn't talk on the phone with her and kept it to text. I stayed calm and focused on the problem. I'm gonna rehearse what I'm gonna say when we do meet. For all I know, she may go ahead and book flights for her and S13 anyway, and I need to prepare for it.

Last night she tried to chat with the kids on FB, and then suddenly just stopped replying to them. she's acting so strange, and it worries both D17 and S13.

I'm thinking about suggesting that we stick to the original agreement: S13 stays with me for new years week. Then I'll suggest that she can take both kids to Seattle for spring break.

I'm having a great time this weekend with my kids, and I'm surprisingly feeling a little detached from her, like I don't need her and these problems. I'm not sure what to think about that.
