Sorry, but this reads like an invitation to betray one's partner.
Yes, I could also read it as "love the man you feel for now even though he isn't the WHOLE man you are bringing him back into being..."
I could read it as love the man who is now, waiting for his future is futile...love him as HE IS. THAT I am happy with..but this song way too easily invites one to commit infidelity. lol
Sorry but this is advice from a musician...hardly credible where long term relationships are of import. LOL
