My H also wants to be "responsible" even though he left, as to lessen his guilt for leaving and not dropping the ball on his responsibility to his family (what a joke considering he left)!
Oh yeah, this is a real kicker isn't it. My W is doing the exact same thing. She doesn't want anyone to be "the bad guy", etc. She doesn't want to face how much she could be negatively impacting our D, etc.
I feel like I've been very accommodating, all things considered. She's allowed to come in/out of the house whenever she wants and I let her take our D 2-3 nights a week to her crazy sister's house.
