WAW having an A but she denies it #2

[shodan]

I discovered the A on Sunday, when she was here in Boston. This is when I found the text messages. She of course denied it and I just tried to believe her. She then left for NYC on Sunday afternoon. I really figured it out on Monday morning, which is when I texted her that I knew who SG was. So I have not seen her since Sunday. She gets back tomorrow.

The kids asked if we could do a dinner out Saturday night, so I am planning to keep that promise.

Under the Plan A assumption, I would have booked a yoga class for us to go to when she gets in tomorrow and then made a res at a restaurant for the four of us. On Sunday, we probably would just chill, maybe get some coffee/breakfast with the kids and do whatever came to mind. What I don't want to do is get in a competition with her to see who can "be the better parent and not involve the other."
