Thanks, Becca!!! I do know I did the right thing so that's good.
An hour or 2 later, I got a phone call and the kids are on the phone to wish me Happy Birthday. D9 had already wished me that and given me a card but forgot she did, so I reminded her b/c she feels bad about stuff like that. S15 did forget, but said it on the phone call. I think X interrogates them about stuff (from what D9 says) to find out what's going on with us, and they must have said they didn't wish me happy birthday, and he had them call me. Actually a nice thing to do.
