I hate let's friends theory. It is hard for me to be just a friend. I tried that before and when she comes to my house we cuddle each other, watch movie and ended up sleeping together. Do friends do that?. Well, let her be your friend, however do not let her run your life. Make yourself busy, go to a gym, hang out with your buddies,… bla, bla…
Move on…
If she wants to talk to you, do not blow her off… You have to respect her (no matter what..).
