To me, this song was more about a girl who is trying to resist the charms of a guy who is a bit of a womanizer - he can have any girl and he knows it. And the singer has seen the girls whose hearts he's broken and she doesn't want to end up like them, so she's resisting him.
"Cause I'm just a problem
for you to solve and
watch dissolve in the heat of your charm"
She's afraid that once he gets her to like him, he'll just throw her away, and she'll be just another silly girl.
"so do me a favor
if I should waver
be my savior
and get out the gun"
