Hope I can help
Hi CuckLuve, it sounds like you don't want to lose her. While probably it is a done deal, there might be a couple of things you may try to bring her back to you and probably recover that love that she had once for you. Now here is the key part: she says that it is not because there is someone else, that it is because of you. That gives you some hope because it means that if she is telling you the truth, then maybe, maybe, maybe, if you change a few things you may gain her back. If, big "IF"....if however she is lying to you and there is indeed someone else that she is leaving you for, then there is not much you can do.
A good move, that rarely fails on bringing back the woman you love is to make sure that she sees you, or gets the impression, that there is another woman, and she better be very good looking, that is pursuing you. I dont know how you are going to do it, pay an ****** if you have to, but do it. Nothing leaves a woman more confused that the realization that there is another woman who is better looking than her, that is attracted to her man.... she immediately will think that maybe there is a good quality about you that she is failing to see. The good part about this move is that if it fails to bring back your wife, then you do get to go out with the other woman!
If you need to try some moves, don't hesitate to PM me.
