Thanks for your comments, Generosity. I decnided not to say anything because, as VH says, he wouldn't believe me anyway.

He must be okay with it now, anyway. I was leaving on Saturday morning, but my friend (who is driving) needs to go on Friday. I told her I had to ask H if he would mind changing his visit with the kids to a different day.

This morning, I emailed H and asked if he would visit on a different day. He asked when and I told him sometime after 1/4. He said okay.

So there you have it folks. My H is okay with me taking the kids on my weekend fling now.
