WAW - is it too late?

[RVM]

So, I picked up the girls from school yesterday and they asked about the weekend trip they've been excited to take. This time I took the opportunity to tell them I wasn't going with them (in a very light hearted, casual tone) this time. They asked why, and I told them I just had personal things to take care of at home, so it'll just be the ladies this time. They were fine with it and made no expressions or comments to indicate any concerns.

Later, I made dinner for the family, and in the middle of dinner, my oldest D told my W that I wasn't going on the trip. My wife looked a little taken back, but quickly replied, "yes, it's just going to be a ladies trip this time." My youngest then said, "aw, I'm going to miss you Daddy." I replied, "I know, I will too. But, you all will have a great time. Plus, I don't think you've ever gone away with just Mommy before, so it'll be a new experience"

Don't think my W appreciated that comment much as she made no comment and was just stoic. We quickly moved on to another conversation. Was that comment the wrong thing to add? Or was that a NGS comment?

Anyway, later on in the evening when the girls were occupied in other rooms by themselves, and I was reading a book, my W comes up to me and says, "so, how did you explain why you weren't going away with us this weekend?"

I replied, "just told them I had personal stuff to work on at home and also actually had to go to work they day they were coming back." (I stifled my gut reaction to say, "the truth!")

She looked a bit upset, and said "OK. I just want to make sure I have the same explanation if they ask again." Then, she left the room. And, I went back to reading my book.

After the girls went to bed, I left for the gym (as I have been doing almost every night of the week now. I used to go in the morning.)

Even though I would have a good time on the trip, it felt like a small victory for my self-esteem to not cave in and go on the trip with them.

I do feel like I'm trapped in some sort of Cold War stand-off right now, and that she is trying to wear me down so I file for D so she doesn't have to. I guess that's a standard MO of WS.
