Have you guys talked about a formal financial separation? (you've probably said and I missed it)
While he's in far-away land it will pay to protect yourself and the girls financially.
Anger has it's place and it can be your friend - use it while you've got it.
Hurt ... yeah, I know about hurt. Not sure what to do about that, but accept that in time it dims - a friend of mine whose been separated for 3 years reckons the hurt of a relationship crisis is like childbirth - at the time you can't think of anything more painful, but when it's over you have a whole new life.
Compassion? only when he deserves it - and he probably doesn't deserve it at the moment.
Keep going.
