Deployed Soldier/Father needs your help

[Greek]

"I wouldn't say much about the OM other than to tell her that you aren't willing to live in an open marriage. If she feels she needs to continue a relationship with him, she'll have to find a new home to do it in."

Ok, but how in the world will that work? Especially after she has ALREADY said that she is done? She might just say "so what" I won't be there to make her leave the home. I am just so confused. Anyone? What do I say to her? What boundary do I set, and how do I enforce that boundary after I leave? I'm willing to do this, just need the guidance and wisdom. Thoughts?

Talk to your CO. You need help with this. You're not the first guy to have to deal with this. Look for this help.
