2, you would be living a nightmare...wife gets all the benefits of marriage and gets two weeks a month away for herself. Would you be taking advantage of that arrangement the same way or would tou be holding out hope she will come around eventually?
You still get to fix the house, cut the grass, have no personal space, all on joint finances, all the while there would be no intimacy or benefit for you (because you will not be able to truely move on from this - i see lots of anger and resentment in your future). Are you a jealous man, what if wife decides to bring someone home to your shared bed when it is her week to keep it warm...you get the drift?
