Confused newbie

[dday]

Ok, game plan:
Don't initiate contact
My stuff will be moved out when she gets back home (we are doing the shuttle parent thing...kids stay, parents rotate. That will change now that I have my own place)
Pour myself into making my rental feel like "home"
Do stuff with friends
Take the kids to do new things
Be the best dad I can be
Do some activities that I haven't done due to family obligations


How do I handle interactions with her? Only kid and legal stuff? Be attentive, but offer nothing but validation? We will see each other at baseball games 2 or 3 nights a week. Do I sit with her or not?

I love it that I have found this supportive site, and I appreciate the advice!
