JMO It seems like you are expecting miracles-he has only been in rehab for 2 months-he is still struggling to stay clean-he has to work on his recovery and you have to work on your own. Certainly he knows the hell he put you through but he is not able to talk about it yet-he will when he is ready. My AH did everything but steal. One house sold, cabin cruiser sold, CDs cashed in, etc. There is almost nothing left. He is in prison because of meth and in a 6 month program for substance abuse (the first time in 34 yrs.). He seems to be doing extremely well and beginning to talk about all the damaged years because of his addications. I backed away with "advice" this is his recovery and I have mine. Seems now we are talking about each and the two programs mesh.
Try to focus on yourself and child and allow him to focus on his recovery. It does get better. Baby steps, hour by hour, day by day and hopefully year after year.
