Pin up the undies on your bulletin board in your apartment.
Ok, just teasin'....... But I would either 1) keep sending them back without a word or 2) throw them away every time. If this isn't an accident, its a pathetic mind game. And remember, you are above and beyond this. You are nocode, darnit. You are taking the right path. Don't follow her down her path. Don't.
We are in a no-fault state as well. The atty I spoke with though, said it can't hurt to have physical proof of an affair. It bears no weight in court (although most judges frown on infidelity), but it CAN be used as leverage in negotiation. For example, the atty told me that he could go to H's atty and say "Look, we have nasty proof of a lengthy affair, occurring sometimes in front of the children. I think lwb has been through enough. Instead of 50/50 on the house, why don't we talk 30% to H"....
