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

[Awoken]

I got an email from W this morning. She's a little upset because S13 mentioned to her that I may not be taking the kids out of town this weekend. Evidently W invited one of her friends to come and spend the weekend (a pro-divorce friend of course). My agreement with W was that we would communicate about our exact travel plans for this weekend before I left with the kids.

I replied via email that I wished she had communicated with me about her friend coming. In light of her filing for D, I couldn't afford the trip I had planned and I was looking for low cost alternatives.

She replied that she and her friend would be using the house, but would try to stay out of the way.

I'm on the fence: do I stay home for the weekend and hope that W decides to spend her own money finding a place for her and her friend (unlikely), do I stay home and deal with the tension, or do I go ahead an head out of town despite the cost?
