I agree with anna. Dont continue to hang D over W's head if you dont plan on following through with it. If you do intend to, then there is nothing more to discuss with this board. Being one of thousands on this board that are facing very real challenges of keeping our Ms together with the threat looming, I personally dont like to hear D being used as a weapon by anyone.
That said, If you have explained clearly to W why you are acting the way you are, and she continues to behave in the manner that yu have outlined, then let her know that you are staying at the apartment to work things out for yourself, and that you would appreciate it if she would limit contact with you for a while to figure out what she wants to do.
