Why me?

Why me, I loved you so much,
we only went out for about a week
but, ask my friends, they all know
I talked so much about you, now, I'm weak

My sister's going out with your brother
It was cute when we were going out too
Sisters with brothers, doesn't get better
She'd marry him, and I'd marry you

Then, you broke up with me
Ended it all
It's called "falling" in love
because you physically fall
