"Says he will stop drinking if I would just come back home" First of all, he needs to find it within himself to quit drinking and not use you as the reason why he quits. My AH just recently quit drinking (for the 3rd time) after he realized (for the third time) that drinking makes him so terribly sick and after just 1 day of binge drinking he literally cannot get out of bed, gets the shakes so bad and is sick as all get out. Hence the reason why he ended up in the hospital (for the second time). He has to quit on his own and there are no guarantees that they won't go back. If you feel you cannot trust him, then my suggestion is to wait it out and see what the future holds before making any commitments to him. He has to be committed to himself before he can commit to you.
Hang in there........
