How does this work?
I know of a few couples where the female is more dominant than the male, yet adores him to an endless degree.
I have no issue with this at all

It just confuses me.
It actually seems to me that some girls are turned off completely by the "Big Man".
A female friend of mine rejected what she described as "easily the biggest ladies man in the school" simply because she just wasn't attracted to him. This was probably 2 months ago.
Maybe I'm taking this too literally...too "black and white" - but I always thought ("always" meaning since joining this community) that the man who is desired by most women and is a leader among men will (basically without fail) be able to attract any girl.
Why did it fail in this case?
She is now dating a fairly charismatic kind of guy who is liked by many, but is not your traditional alpha. To the extent where she dreams of marrying him...after so little time. She met him one week after her encounter with Captain Awesome.
?
This very example puzzles me.
I suppose my question is:
"Why would she pick the more beta option, when presented with what is stereotypically seen as a much better catch a week prior?"
