You might not worry about saving the marriage, save yourself and maybe through her own experience the wife comes home. Maybe she will not, that is the delimma. You have to save yourself anyway, so you need to make a list of things that you have to do and get them done.

About the wife, the OMW phone call on monday and maybe talk with her and get her sort of motivated in shaking OM up to save her marriage. What he's doing is not good for her kids. A W will go to almost any extent to protect her kids.

Save yourself, hopefully OM is shaken up hard enough to dump your W. Maybe you'll take her back maybe you won't, maybe she'll come back hard after understanding she put so much on the line, and maybe she won't.
