It's taken me a long time to get the whole "detach" thing down. I could always do it for a couple of days but then I'd be right back in there telling him everything he was ruining with his actions etc. Good for you for figuring it out. You won't be perfect at it, but it does get easier because you get healthier and you realize it isn't worth it to fight, pursue, blame, etc. It does no good.
