Need advice for a WW who left

[dwh15]

Thanks guys. The only reason I mentioned replying about kids is because it is Friday, a night she normally takes them, and I hadn't heard a peep and neither had any of the kids. So here's the full TM convo:

WW: What's up?
Me: (hour later) Hey. Kids were asking about tonight. Did you have plans?
WW: Talked to S18. He was coming over after working out.
WW: Possibly go to my friends house.
Me: So are they set for dinner?
WW: Yeah

That was the end of it. I specifically asked about dinner plans because a couple of weeks ago, after the big money blowout, she had said that she would not be making dinner for the kids at all and I needed to provide it before they came over. So I basically confirm or have the kids confirm ahead of time on the nights they see mom. Yes, it's totally ridiculous, but my attorney recommended to let it go and let her just keep digging that hole. So if I have to make dinner for my boys 7 nights/week, that's what I'll do. Fortunately, she seems to have calmed down since then and is back to providing meals, but as usual, it's mostly just S8 and S18 that goes to see her. Tonight, I'm with S10 and S15, the same way it goes down 95% of the time.
