Sounds like a decent FD with your kids and that is the main thing. You spending time with your kids!
The WS behavior is all over the boards. Who the heck knows what was going through her mind. Maybe she knows the D is progressing and being a 'family' is too tough on her mind. Maybe she was really tired?
I guess just keep on being you like you said before. Be the good dad to your kids and the rest is going to work out whatever way it will.
