That Feeling

You give me that feeling
People write novels about.

You know, that delicious,
spine-tingling, breathless,
butterflies-in-my-tummy feeling.

That feeling that makes me terrified
Of losing you.

That feeling that makes it hard to sleep
When your arms aren't around me.

That feeling that makes your laughter
Seem, oh, so infectious.

That feeling that makes me smile
Without realizing it.

What's that feeling called?
Oh. I think it's love.
