If she wants to reconcile, the fact that you have her blocked will not be an impediment. She'll find a way to contact you.
I respect that you aren't done, and that you want your W back. If that's truly the case (actually, even if it isn't) then focus on you. That's all you have control over. Be the best you you can be. Maybe it brings her back. Maybe it doesn't. Either way, nothing can take away from that accomplishment!
But you HAVE TO take your focus off of her. HAVE TO. Your mental health REQUIRES it.
