I interpret the important line, "And if I know you You'll find me someplace new", as sso:
Me not as a person, but rather "me" as emotion, love/excitement.
As if, 'You found and fell in love with me, but I know that you will soon find another love in someone else"
It's "a waste of time" because we both know you're just going to run off with another "Me" again just like you always do.
