WAW w/Exit Affair or WW? - Divorced Anyway (4)

[BL42]

I'm so frustrated tonight because once again the kids came back unbathed. I don't mean for a day or two...for the entire week they hadn't had a bath or shower. They were clearly sweaty and unclean, and when I asked S6 about it he smiled and kind of bragged they hadn't had a bath all week. Again I'm torn between emailing Ex-W to stand up for the kids' care or keeping quiet because the message coming from me won't be well received.

The other major area of concern is last week we were having a family dinner with me, the kids, and my parents (who they're very attached to), and D2 mentions her great grandma (my W's grandmother) is getting a new house. My parents and I wonder about it but S6 brushes it off several times as if D2 is being silly and making things up. However, my mom knows my son and believes he was lying or covering up for D2. It's not even something he really needs to cover up, but S6 doesn't understand that; the fact he's either being told to lie or even just feels the need to is concerning. Well, turns up great-grandma's house pops up on Zillow so D2 was right and S6 was likely trying to cover it up and flat out lied to us. We weren't digging - D2 just mentioned it - but S6 jumped in trying to play it off as if it wasn't true.

Turns out both my Ex's great-grandma's house (in town) and her mom & step-dad's house (in other state) is up for sale and her mom and step dad are now moving into town. Ex-W's mom had an affair and divorced her dad and the more I'm learning used emotion and psychology to push the kids away from their dad which eventually led to him not even being invited to our wedding (red flag in hindsight I should've dug into at the time), and she spread lies about him all over town. So...I'm concerned about S6's lies and concerned Ex-W's mom moving into town is going to spell more trouble.
