Okay, long story short, she has done everything except say that she is not interested after our first date. I asked her out again and she said she would have to get back to me on when because of her busy schedule (which it is). Now she hasn't called me in a week. Clearly not interested. But how should I approach it when (geez, at this point, it might be "if") she calls back? Should I even accept any kind of invitation of hanging out? Should I even not respond to her? ???
