It's hurting that I can't still talk to her even she is here

Stalk away

I know it sounds easy from my vantage, but I'd think finding a way to move along would be helpful. and I'd suggest getting lost in some music for a while.

Do more things to be emotionally free. Break away of the thoughts encouraging attachment. You can love without owning or having.

Take a break. Get out of here.

Why not?
