Good luck man, I'm at the exact same point as you, excuses for meeting with mediator and confronting/dealing with issues. Even if you don't plan on dating anyone it feels great to get out and socialize and helps build up your own confidence. Women are good at picking up visual cues of how you are feeling and how you present yourself so if she sees your mentally moving on and distancing she will think twice about her disposition and behaviour. I would suggest also getting a lawyer on retainer to go along with mediation, lawyers can send simple letters to her to encourage moving forward with mediation and they'll also give you good legal counsel on what your options are. Have you considered putting the house up for sale as an extra option. Mine right now is suggesting she buy me out but I have a signed listing agreement to push the issue. I have also asked her for a concrete buyout proposal but I sense in your case and mine is a ploy to delay the process because she can make excuses and delay this way. A listing agreement has a set date and creates deadlines.
