I'm inclined to suggest it would be fine to go with her to the fair too. But you have to be really careful with your emotions.
H said plenty of times he didn't mind if I went and did things with him and the boys, which I felt was clearly different from an invite.
If the boys are dying to go camping and they think the fair would be boring, it might not go well.
I agree with FY: don't use this to teach a lesson.
I went with H and S13 to a Mustang car show last August or so, and later he told me he looked at it as a fun "family time" and really wanted me to go, but at the time I was struggling badly with my emotions. It was really hard to act relaxed and normal.
CB and FY suggest finding out more info before you make your decision. I think that's a great idea. And it's only Monday so you have lots of time.
Or is there a way to do both? Camp one two days and one night with the boys and do an evening fair with W and friend?
I and thinking your W will bring up D whenever she feels pressured and scared and will leave it alone when she feels warm and loving.
