There has to be chemistry in a duet, but if you go beyond the point of friendship and attraction, you lose something.
In marriage, as in chemistry, opposites have often an attraction.
If you examine your history, you cannot help but repeat it! Law of Attraction says it is so: 'Whatever I am looking at, I am including in my vibration.'
Chemistry can be a good and bad thing. Chemistry is good when you make love with it. Chemistry is bad when you make crack with it.
