Don't read too much into it. And moreso, do not get your expectations up - in fact, expect nothing.
We just last week finished a 17 day vacation. W, D10, S13 me and another family. W was withdrawn the entire time (other family questioned me on it - was that noticeable), but I had a good time with K's and other family.
Make sure you do that - have a good time for you and K's. If H participates, great, but do not read too much into it.
Treat him politely and kindly. BUT retain the focus on you and the K's. Time together also lets you show the new Sandy!
