From Peter to Wendy. So in your mind try to change the once mentioned "her" to "him" because this really is otherwise fitting from Peter to Wendy about himself. Except the two first lines in the second verse "Take a breath and I try..." ect.
Peter's grown up after all but not really grown up, basically just grown older but still is the same emotional mess 'cause he can't let go of what happened with his mother not to mention open up about it.
