Get a private investigator today...very expensive, but very valuable. Seal the deal. Go to your attorney Monday....get legally separated after you prove the affair is ongoing. Better yet, document that she left the home without your permission or any agreement. Close the accounts. You are off her list. Get her off of yours. She will be nice and seem to cooperate as long as you keep the $ flowing....shove her into her lover's arms with reality that you create.
NCplayer, I'm struggling with this decision now. I've only been at this for three months, but it seems like an eternity. It terrifies me that I could keep this up for years and still not get the results we both desire. She has been really distant for the last few weeks and I suspect that she has started talking with the OG again. I'm on the fence as to what my decision should be, but I'm starting to lean towards filing.
