Billy, a lady May, indeed, always change her mind--so can a man--but it's really not a natural law to say 'they always do'. Some of my ex's would reverse the course of the amazon river before changing their minds about anything. (And of course, many of them would change their minds).
Cheers to that live black lady, she does make a lot of good points. However, I noticed she said in one sentence "The guy is non-committal, pretending to be interested in a relationship, he'd rather jump from woman to woman...and if you're not that guy, your boy is that guy..." a few breaths later she says "Why can't you accept that guy, let him be who he is..."
Lord, if only all women would think about that latter statement more often...
