staying friends with a female who rejected me, but begged me to stay friends with her twice after leading me on by saying I'm the perfect guy...

Thank you everyone for your input. Seeing your insights makes me feel a tad bit saner since I was starting to go crazy thinking I was in the wrong for wanting to end our friendship. Unfortunately, I eventually ended up letting my insecurities get the best of me since my self-esteem was already pretty low when we first started talking due to other circumstances. As time went on, I stopped working on myself and invested in her which lead to it progressively getting lower as the person who put me on a pedestal started to act deceptive in nature. I think the biggest mind fuck of this entire situation for me, however, has to be how she told me in the beginning that she wasn't going to show feelings towards me because doing so would be wrong since she only has feelings for her ex, but then constantly says things to lead me on while stating that she doesn't want to lead me on and that I should move on to someone else, but wants to remain my friend and hang out. I honestly don't think I've ever experienced literal mixed signals in this manner. The only thing I can take away from this is that she is a good person, but must be deeply confused or she's a manipulative person and I herp a derped. This is the abridged version of the situation and only my side obviously, but I'm currently trying to reflect on this situation as a whole to see it for what it really is, learn from it, and hopefully find a silver lining. Any recommendations on what I should take away from this? I know this paragraph is poorly written and I apologize for that being the case, but holy shit it's really difficult to think clearly with all these emotions running through me.
