I couldn't tell you for sure(if it will ever be the same) but I really don't think so.
I'm going to be honest with you. I think you should start thinking about life without her.
This problem happends to a lot of people.
Start letting go of her, little by little.
I know it seems hard but by the looks of it, the relationship is running on empty.
She might start getting annoyed or start looking for stuff in other places, if she hasn't already.

One of the great things about love and heartbreak is that, with time, it heals itself. And then when you meet your next partner, it starts all over:jointsmile:
