Lyric discussion by missme 

I think it's about being with someone who's confused and maybe hurting you but not intentionally, and she wants to swap places to show him what it's like being in her place - "It doesn't hurt me/Do you want to feel how it feels/Do you want to know that it doesn't hurt me?"

i think your meaning is closest for me,

This song has meant different things to me at different times in my life. At this moment, your particular interpretation expresses my present situation/feeling perfectly.
