Analysis of Love?

It makes my fingertips tingle from excitement
As if there were tiny ants crawling on my skin
It makes my stomach feel
Like there were thousands of beautiful butterflies flying around in it
And it makes my heart pump every single drop of blood like if it was the last

But sometimes these ants on my skin don’t tingle, they bite
Sometimes these butterflies in my stomach don’t tickle, they sting
And sometimes my heart really doesn’t want to pump that last drop of blood

Because maybe love isn’t exactly
