Lyric discussion by Oxenbrigg 

Cover art for Raining In Darling lyrics by Bonnie 'Prince' Billy

To me, those last lines is exactly where the song needed to end anyway. "And I know you love me/I know you do..." The fact that he doesn't say it just once, he adds "I know you do" really makes it sound like he's trying to convince himself and possibly the subject of the song that he/she DOES love him. Of course, my interpretation is that this is a dream/illusion and he's just trying to convince himself that one day, this person will love him.

My Interpretation

@Oxenbrigg Yeah, "I go outdoors where it's fun to be" does not sound very convincing either and the way it is delivered I think supports your ironic interpretation.
