Firstly, get her off your dreams. Whenever you're dreaming about her, stop drastically. This hurts at the beginning, because dreaming is so sweet, but you'll get used to it. Then, stop expecting her to call, or text. Don't reach out to your phone in a hurry to see if it's her, it's not. Just bang your wall to the wall if you have to, accept the fact that she's not gonna call.
