I am... She is...

I am introverted, she is extraverted.

I am things, she is people.

I am intuitive, she is data-driven.

I am big picture, she is detail.

I am spending, she is saving.

I am concept, she is process.

I am approximate, she is precise.

I am why, she is what.

I am ideas, she is execution.

I am theology, she is praxis.

That's a pretty good pairing.  :)
