Survival of the Fittest

I think about her, she thinks of him,
to me she's everlasting, to her I'm just a whim.
Why do I try to get so involved?
When will me feelings be resolved?
I want her, she wants out.
Why did I choose such a bitter route,
this route of love, this route of pain?
Is it something we are born with, is it in our brain?
What we try to do is make them impressed,
by acting macho, our feelings repressed.
If we show our true selves, we risk being hurt.
But some risk the pain, and do not get burnt.
Some survive, some do not
I hope to be in with the lucky lot.
