Today you fell in love with him,
and he in love with you.
But what you do not realize is
that I have loved him, too.

But I suppose it's for the best.
If he is happy, I am happy.

So I'll erase the memories
we've shared over the years.
I'll forget about the things I know:
his secrets, joys, and fears.

I'll forget the longing I felt
when he held you in his arms.
And I definitely won't remember
the single tear that escaped my eye
when he grasped your hand in his.

This isn't a great poem, but I just needed to express myself before I exploded. We've all felt this way, no?
