When he came back, have the two of you discussed MC? That is a must! The problem is that when the WAS comes back, there's a "honeymoon phase" that lasts a month or so, and then they start to withdraw again because they're original problems havent' been dealt with.
You've got to take care of that and not rug sweep the original problems. And it needs to be taken care of asap before he starts listening to the voices in his head that caused him to leave in the first place.
