Patience is a horrible word, but you've got to have lots of it smile It's only been 3 months! She is still in the early stages of separating from you and is probably still liking her single life. Give it a few months down the road and she may feel differently about her single life.
What changes have you made to the new improved you? With me I suppose I've lost a bit of weight and never go out looking scruffy now. I've still got a long way to go to be the best that I can be and if he came back now, he'll probably get fed up again after a month because nothing's changed! Do you see where this is going?
Think about what you can improve about yourself or the way you live. As I've said before, how would your W react if she walked through your door right now? Would she walk straight back out or would she want to stick around? Yes she probably does care about you, but not enough to live with you or make your marriage work. When they just leave like that, it s**ks big time! You are left wondering what you could've done better or what made her leave in the first place. My H has been gone 4 months now and although I'm in a better position than you, he still has left me to guess why he went!
In the long term she could come back to you or she could not. You have to be prepared for both scenarios. I know you don't want to think about the latter scenario and neither do I frown This is why the 180 rules and GALs are put into place, to become a better you. ok I'm done nagging now smile
