I'm not familiar with your sitch so I don't know how long you have been going through this with your XH. I do know that my H got two DUIs (within one week of each other) back in the throes of his affair last year. I thought that he had hit bottom, but he didn't. When he got arrested for assaulting OW, I thought he had hit bottom (and that the affair was over). I was wrong on both counts -- he bounced right back into MLC and the affair actually picked up steam.
Since then, he has lost his job, been ordered into rehab, lost most of his money, is in debt up to his ears, and admits that he is the most miserable person on the face of the earth. But hit bottom? Nope.
I know that everytime I got my hopes up, they soon came crashing down. Nothing I ever said or did made much of a difference. Every situation is different, but my only advice is to stay busy and try to take your focus off XH. I personally wouldn't call him or offer him any help. It seems to me that he is in denial, and any "help" you might offer could backfire.
