<human>: Give me a shortened version of the text

In retrospect of all my past dates/SO's/etc, I noticed some trends that troubled me. While they usually showed a lot of chemistry and enthusiasm early, many of them became "flaky" and unreliable soon after. One of the more recent girls I dated would have a great time and show a lot of interest in me (and would even initiate kisses/touching/etc) when we went out. However, it seemed impossible to actually get her to go out. We'd make plans and then she'd later back out, or I'd ask her out and she'd "have to get back" to me or change plans. But when we'd finally go out, she was far from being disinterested.

I started noticing that my "type" seems to be pretty flighty and unavailable, although I consider those qualities strong turn-offs. They tend to be more self-centered than I'd like in a SO and I hate to stereotype but it turns out most of them have been only children (no siblings). To the contrary, I'd list "selflessness" as one of the most important qualities I'd look for in a SO.

But... I can't blame them entirely because the common component is me. What does this say about me? How should I change my approach or what should I look for to find more compatible relationships?
<bot>: I usually go out with unreliable/flaky women but that is not conducive to meaningful relationships... what do I need to change to find more compatible women?
