because.... some gals love a challenge to "CHANGE SOMEONE"
or be the "CAUSE OF SOMEONE CHANGING" -
then they can boast to their other gal pal of their accomplishment forever.
agree. most of these girls know.. they just don't want to accept it. or they think they will be the one to make the guy finally commit.
just like those girls who say they'd never make the first move. they want the guy to 'work for it'.
