Okay the part-
"If what they say is true, you're a boy, and im a girl. I will never fall in love with you" Could mean something other than lesbians...
"If what they say is true,"- okay so like what they say about love and relationships that it's hard and filled with heartbreak and sorrow.
"you're a boy, and im a girl"- You are boy obviously and I'm a girl obviously
"I will never fall in love with you"- so I can't fall for you cause in the end it will only hurt
So to go along with the rest of the song she will only play with boys not fall for them cause she doesn't want to get hurt
