I can't have you

To watch you walk away is the hardest thing I’ll ever do, And you’ll watch me reuse this line for another guy in six months.

When I finish the battle within me,
I pray I haven’t begun a war with her.

Because no one will love her the way you love her,
But no one will forgive you, the way I forgave you.

But maybe we are two ninety degrees trying to be a triangle,
A coin can’t have two heads,
And I can’t have you.
