And this is what I'd say to the next girl:

Don't get close enough for him to tell you you're worth something.

Because at some point, the roles will be reversed
And you'll be left wondering what he's worth

And the only message you'll hear is silence.

But maybe this is a lesson in how not to hate someone who doesn't hate you, doesn't love you, doesn't care.

Because this is what he's taught you: that you are only worth his time under certain parameters.
