I can't be him

The moment I saw you, I knew this is it.
I left all I had, I sinned, I admit.
your eyes are the very reason why I'll never quit,
in finding the purpose, why the two of us had to meet.

I know I love you, but you love someone else,
this life without you will be but a mess.

I'll wait for you, all the best, I will try,
I'll wipe those tears, there are no goodbyes.
I'll never be him, I'd rather die,
walking a hundred miles, just to see your smile.

This is a series of my daily thoughts, why I can't be just like him.
