Hi AFG. Im so sorry, this is one of the worst things that I have heard of somone doing. And I agree with Greek here, moving his crap out is NOT retaliation, its protecting yourself from him doing this kind of thing again. And I agree with puppy too, I think that hes scared, and I think that a sweet little line like that will scare him even more. Let him live with his skank, if shes not classy enough to feel uncomfortable being with a man when his W is in the next room is perfect for him!
Retaliation would be setting his stuff on fire, or spraypainting his truck, not removing his things from the marital home after he has expressed such extreme disrespect to you and your M is very different, and I dont think that it would hurt your case one bit. You dont need him and his kind around you, so set a boundary and get him out of your way.
If you are willing to commit this much to a man who totally doesnt deserve it, then someone is going to win big when they get you, so let him go have fun with his chlamydia, I mean gf.
I guess I gave the wrong finger to the wrong man...
