I would never suggest you make light of this serious situation. It's good that your son is able to talk to you about what he's going through. Is there anyone else he can talk to? Counselor, pastor, uncle, etc.??
The problem I have with the concept of "stealing" a person, is that it takes the responsibility off of your H. Think about it, if she did "steal" your H, then he was a helpless, mindless, victim, unable to change this situation. This is certainly NOT the case.
Unless you're thinking to take all responsibility for this away from your H and just blame OW??
Sorry, just a little confused.
Your S should not be on her FB page - it won't help him. Is this OW a person that he knows from before the A?
And you're doing great, by the way. I've been following along for awhile - you're getting stronger.
Also, I checked out BillyClay's thread. It's hard to post, he seems very confused.
