There's always hope, but I think the best possibility here would be months or likely years down the road, if at all.
Someone needs (I haven't read every post) to tell you that most likely she is gone forever and you should plan that way. Do your best to make yourself the person you always wanted to be, live your life, and if she comes back that's good.
You are doing the right thing in not chasing her. If you do you will drive her away and the chance of her loving you again is zero. Negative chance if that's possible.
You need to know that she is not the only one on the planet, and that if you mess things up with this one, you can always fix yourself and find another. I know that's not what you want, but we don't always get what we want. It's just life.
ACCEPT that she is gone and isn't returning. If you want a chance with her, give yourself a time frame for her to return. At the end of that time frame when you've got your life like you want it, ask her if she'd consider giving you another chance. If she says no, start dating and never look back.
I should say that once a woman falls out of love, I have personally never seen it return. So hope, yes. Lots, NO. Just realism, not pessimism.
Btw, if you start dating other women, she will find out and you have no chance at all.
You likely won't be ready to date mentally, anyway. I personally think you should give it a year and if she's not interested then, start dating other women.
I really think she's gone. I just hate to tell you that since you're looking for hope--- I believe that hope will keep you in limbo and drive you nuts, but it's your show.
I do wish you luck.
Thanks. This is good. If I can't hope for this relationship, I can hope for the next one.
