Well, you could be obsessively bothering her or she could be just plain pulling away. I know this guy who said something like that and he was just calling her literally at least 5 times a day. I think you should give her 2 more weeks and if she does not shape up start talking to other people. Not necessarily have sex but to just see what are your options. Just to give you a little dose of reality that there are other women in the world. You said you can't picture yourself with another chick well force yourself to picture it by going out and talking to other women. That is it. I hope that helped.
