She just wants to be friends

LetsBond answers:

If every time you call her she tells you that she just wants you to be friends or that she is kind of seeing someone at the moment, it is probably because you were doing something wrong when you first met that made her place you in the nice guy category. You probably do not know how to create sexual tension and attraction.

You could start by learning something about creating sexual tension and attraction and even if you don’t quite get how these things work at first, keep doing them so that you will start to understand sexual tension and attraction better.

For example, the cocky and funny technique is great to create the tension and attraction early on, without being necessary for you to get together. You could also ask for e-mail addresses and not only phone numbers because from my personal experience, I have learned that women tend to respond better to e-mails than to calls.
