In your situation, living under the same roof is KILLING your chances of reconciliation. How can you work on improving yourself when you are living in fu*ing misery. Personally, I do not understand how you have been able to deal with this sh*t for as long as you have.
YOU NEED TO PREPARE FOR DIVORCE AND GO ON THE OFFENSIVE. You've got a nice little nugget of information regarding her visit to a lawyer, you should do the same. You need to start preparing for the worse case scenario.
As we have been discussing, you have chosen your family home as your battle field. The battle will not last forever. One party will give and retreat. Looks like she is getting ready to pack up the tents. She is at the point where she no longer gives a fu*K.
My opinion... the only shot you have of saving your marriage is if you agree to move out ASAP. That will give each of you a chance to work on yourselves and prepare you for a much better marriage.
W and I went out to an awesome 4 hour lunch today. We both agreed that we are in live and truly like each other more than ever. We both made MAJOR changes during our separation.
Think about it... If you would have separated 3 months ago, you may have been back together in another 3 months (took me 6 months). START NOW.
