I think the song is about going into a relationship with someone who is very open about the fact that they aren't looking for something serious and that they aren't planning to settle down any time soon. Although she accepts this at the beginning and know that they both have busy lives, she can't help but get emotionally attached and fall in love...longing for more than what was agreed. The last few lines make me think she is talking about someone who is also a performer.
