Hopefully his wife will divorce him. If he has one shred of decency he'll give her all of their assets. Of course, his legal bills will wipe out savings...
Hopefully she'll see a counselor and best of all, in time she'll meet a wonderful, kind, capable, fun, interesting man who will be everything that Pervisoid is not - a man - who will love  her and the kid. 
And they will live happily ever after.
The End
