Yup! Chemistry is either there or it's not. Don't you agree that many times chemistry is confused with love, though? When the chemistry dies we think that love died, but it wasn't love at all to begin with. Love isn't just a feeling. There has to be Action behind it... and commitment.
Oh, Hell!! This opened up a can of worms for me.
