I also didn't follow all of your points, but there are a couple things I want to point out.

FYI, I'm a girl and engaged to the only man I ever really been with, so I don't know how helpful any of this will be.

There are people attracted to all kinds. It's been studied, actually, that like is attracted to like (point in case, my fiance and I have been mistaken for brother and sister...). Similar body types, etc. tend to go for one another. I don't really know why, but for some reason it happens.

All sorts of people find love and happiness.

Next, there is such a thing as too big.

I think what makes someone attractive is their self-confidence and self esteem. You can't love someone who doesn't love themselves. But then, you can't really love someone who is only in love with themselves, either. There has to be balance. If you think you are worthy of love, and that you are happy with the way you look, then you will find someone. And yes, that is part of your personality. Negativity just pushes others away.
