What--it has been just a few days since you last saw him. Do not make assumptions. Learn to live and do things on your own. Sure he will be in the back of your mind but put your best foot forward and carry on. Don't badmouth him or think about ow as it is so not worth it.
He is not himself for now and it is going to take a long time for him to get thru this but you have to make changes for yourself.
Think about you and your kids.
