Hang in there man. You dont know if she is putting on a front everytime she sees you or not. In your mind, she doesnt miss you at all and you are the only one having trouble with this. That isnt the case Im sure as many of us felt that way.
She could have used your stuff as an excuse to see you. Im not saying that is 100% the reason here, but you dont know. Thats all Im getting at. What she is doing is normal really. Just keep your DB attitude and methods going. Dont show her your emotion when she stops by. I also wouldnt discourage her from coming over or anything when you are there. You want to see her and this is a chance for you to show off some of your changes a bit.
She acts like that right now because her guard is up and she isnt going to give you any signs that she values you as a romantic partner right now. Take it from me though, it can turn around in the blink of an eye. It happened to me and Thornton. There is no real explanation as to why, but it happens. Keep at it and dont give up.
