Now you're cooking! As parkema says, you don't need to not talk to him at all...and actually you can't because of the kids and money, but on your terms now. No more enabling. No more emotion shown to him or R talks. Calm, practical, detached...and start making a GAL plan which is more fun than DIY!
You can have the odd duvet day, of course you can - this is a s**t situation and you are allowed to feel how you feel. Time for you and time for the kids now - let him stew and start dealing with the practical effects of his own choices.
