Just a quick update. I've managed a commitment to myself tonight to not drive around to her house and all her other "friends" houses to see where she's sleeping tonight. Had a couple of dumb nights doing that stupidity.
Then, had a tough time with D12. She was crying and missing her Mom. So, I went over to cheer her up and to support her and give her a hug and then, this was new, she said that she misses Mommy and Daddy together. I didn't know what to say to that. That was the closest I came to breaking down in tears today.
I'm finding that detaching also takes a little work and that snooping is the enemy of detaching.
