<human>: Can you provide a brief rundown of the text in within 3 sentences?

Looking back, every relationship that I've avoided was because I felt that the girl cared more about me than I did about her. It made the relationship feel boring and like a chore. On the other hand all of my good relationships were because we both sort of fell into it. Neither of us really cared too much but enjoyed each ohers company.

Then when I started to show that I care more, they would sometimes start pulling away.

Why are we attracted to people that we think don't care about us? Or if I'm the only one why do I do this? Why am I turned off by a person that really cares about me and wants to be with me? Does it have to do with my upbringing? How I value myself?
I'm in a gloomy mood. When I'm in a good mood I have this idealistic mindset that I'll find someone that will reciprocate my affection perfectly without going over the top. 

When I'm feeling good I don't care about girls that don't care too much about me because I live in a world of abundance, am a good catch, and it's their loss. I even think this way about my ex when I'm in a good mood.

After re-reading what I just wrote I think I'm just getting over this ex and need to give myself enough time to do it completely. I always cut myself short of healing and call her up, attempting to impress her, when all I really need to do is be myself and that will be enough to attract someone that will be a good match.
<bot>: Why am I sometimes attracted to an ex that no longer cares about me as much? Is it just wanting something I can't have? Fading love?
