This entire verse is about a girl who he gave a chance to come along with him on his way up to the top and she ended up letting him down for another guy. This final line concludes it all by telling her she can take the guy, since Wiz doesn’t need her.
She can go away and take whatever he valued in her before, because he’s got bigger and better things to do now.
