Paperwork almost done, but not me!

[figure-it-out]

For what it's worth, I have spent holidays much the same as we always had for the past 2 years.

I felt the same way you did. H and I were getting along great, kids enjoyed spending time with family and I was able to show H the "new" me.

Things changed this past week when H introduced S to OW. I no longer feel I can be at holiay funtions as a "family". The majority have always been at H's family's homes and I don't think I can deal with seeing OW there. He hasn't said specifically he was bringing her but he didn't specifically say he was introducing S to her and did anyway.

I am sad I will not be able to spend that time with my children or with H's family who I love with all my heart but that's the reality of my divorce and how it will be going forward.
We worked out a preliminary holiday schedule weeks ago. I told H at that point I would have no problem keeping holiday traditions in tact until he brought someone else into the picture and then I would proceed with the new schedule.

I would say continue on until you can't. No harm in giving your children some more good memories as long as you're comfortable.
