"Jealous"

I get jealous because I care.
Even though I know you don't care.
I know I have no right,
Because I am not anymore part of your life.

It gives me so much pain
Looking both of you happy under the rain.
You told me she is just your friend
But you treated her like a queen.

Hiding,
for you not to see me crying.
Smiling,
But deep inside I'm dying.

Promise I'll run away
For me not to bother you anyway.
But before I leave please take care for her
Like what I did to you when we're still together.
