Step 1
Recover from the shock
let the emotion roll through your system
Breathe in and out.
Don't throw up.

Step 2
Plant a big fat smile on your face
Say I'm totally happy for you.
Wow what great news!
Don't throw up.

Step 3
Burn everything you've ever written about him.
She's your friend, she deserves more than you
You can't compete
Don't throw up

Step 4
Revert to what you're good at
Making other people happy.
Get them together
Don't throw up.

Step 5
Move on
Attempt to 'hook up' with someone
Fail miserably
Don't throw up

Step 6
Be the third wheel
And the reason why they'll be together.
Watch him pick her over you over and over.
This time, actually throw up.
