<human>: Can you condense the text into a few key points?

I've been through a tough patch dating wise lately (for quite a while, honestly..), and frequently find myself thinking about my ex.  I've dated a few women who really got me going physically, and a few of those who were also compatible for me.

Unfortunately, I've realized that the set of people who are compatible for me is pretty large, compared to the set of people that really get me going physically.  I have a weird "type" that isn't overly gorgeous, but very "cute."  Women tell me I'm quite attractive, and that my prior girlfriends haven't been way out of my league or anything, but I still find myself wondering.

I was deeply in love with my last ex (who broke up with me because she wasn't feeling a lifetime commitment), and I still occasionally see her around once in a while, or pictures of her mutual friends post on Facebook.  Whenever I see her I find myself feeling that insane "spark" deep in my heart, and it really makes me feel horribly because I know that the feeling I'm getting is me being upset at myself because of the insane chemical attachment to her.

At some level, I know that it's not that my ex is the most gorgeous person in the world, but she was very much my "type," and I find that very few people set me off like that.  Of course, it wasn't meant to be, I don't want her back, but I wish that I could take a magic pill that would allow me to feel the same sexual attraction to new objectively good women as I did to her.

The problem is that I do meet a few women I feel this thing for, just a very small amount, which I feel hinders my ability to find new love.  As much as I know I'm a complete asshole by judging women for their looks, I also want to know strategies that people have employed to shift their ability to become attracted to other people.
<bot>: having a really hard time becoming attracted to new women and frequently find myself drifting back to the chemical feelings towards my ex, want to know how to properly detach physically and view a wider range of women as sexy.
