As expected, S11 called W several times until she finally came over to say good night to him. I talked to her for a few minutes before she left, basically said that of course she's welcome to come over and do that when I'm with the kids, but I'm also going to be more present with them, which means that I will be spending more time at the house on her nights. She wasn't happy about it, but I'm not going to let my kids get distant from me to make things easier for her.
Before she left, I said "you know there is a simple solution to this"
She said "Yeah, us all living together again"
I nodded. She kind of shrugged and left.
Not sure if that seems like pursuit, or is against the DB way of doing things, but I simply stated what we both know, and nobody has been addressing.
