Cover art for Let Me Go lyrics by Melissa Etheridge

I think that this song means that she wants a real relationship with the person that she is with and she's wondering if she's only a temporary fix and desire or stand in for that person and if that is the case she wants them to "let her go" because this person is an obvious seducer who is not for real. Meaning that she wants a "real" relationship not a temporary fling.
