Someone can change their mind about their affections every day. Your emotions and hormones dictate who you are attracted to at that particular moment. It makes me think someone who changes their affections that often however are not looking for a serious relationship (or ready for one) or they just haven't found one person that they really like enough to settle down with. Or that they hook up with someone before they really get to know them.
Indecisive, inconsistent or summarily, a fart in a windstorm.
