Very frustrating thing and has been happening to me for quite a few years now. (I'm 30 now btw) I always seem to be looked at as a friend by females and not as someone they want to have a relationship with. I am very close to one female now and we get along great and I recently brought up to her that I'd like to try and see if there is more there. She gave me the "I dont want to screw up our friendship if things dont work out" line. Which may be the case, but makes me feel like I'm not worth even trying for. And what makes it harder is that she will flirt with me. Which makes me think maybe she is changing her mind, but then she acts upset if I bring up trying to have more with her. Am I crazy? Or is she messing with my head? The whole thing is frustrating.
