I think this song means, that he could never really get the girl he wants, but can still not let her go. He loves her too much to just let it go. Maybe he thinks there's still hope, but at the same time he thinks he wants to let go but his heart gets the best of him.
"so what if I change whats wrong with it"
maybe this person has changed in the eyes of his friends, but he denys it, he still thinks he's the same person, even before he met the girl he fell in love with.
"that girl is like a sunburn"
she either is a memory of the summer, or it's something that bothers him for awhile but goes away, its a reoccurring thing.
