I agree with Sandi, I truly do believe the guilt is eating them alive, some more than others.
Emmess, we are here for you, we have seen you transform into a much better person, the drinking has lowered, the anger has lowered, now you need to diminish them!
MOVE FORWARD, get the ball rolling. You will feel so much better taking charge for YOURSELF. Stop this self pitty, it is not healthy, you have tried all that you could.
It is not your fault, they clearly chose that path, you need to pack up and look after YOU and your children now. GOD is with you.
