Steady, getting caught up here. You sound like me in some ways: I do great with the big picture stuff but I always question the little interactions/niceties of what I should be doing on a day to day basis. On one hand, it's nice when things are pleasant. On the other hand, you don't want to be too friendly and make the WS comfortable with their bad behavior. While knowing you're to be living life for yourself and kids, you always want to behave in ways to draw WS back. Otherwise, you wouldn't be here on a DBing forum! LOL
My sitch is different in that H and I are not separated, but it's still hard to discern at times what to do.
