Chemistry is unrelated to how much two people have in common.

Chemistry is a wonderful, free spirited beast and it comes and goes when it wants to.

You can’t fabricate it. You can’t summon it. You can’t squelch it.

That’s part of what makes it magic.

I think intelligence and a willingness to be playful create that “spark”. It’s all about the interest and the energy, when those two things are high, magic can happen!

For me it’s been opposites attract, he’s very serious and quiet, I’m very outgoing and talkative. It creates a great sort of “friction” that keeps things fresh, never boring.
It’s OK to be with someone who is radically different in personality than you, it creates breathing room and space because you have to get away from them for a few moments at least, or you’ll go crazy. I enjoy this difference, it creates a respect as well as a wonder of “How is she/he like that?”
On the other side of the spectrum, you must have things in common where they really, really, really count: shared values and respect, shared idea of the future. How do they feel about kids? Are they open to changing to your ideas of a family?
Do they believe cheating is off limits, how about drugs, staying out all night, eating healthy, gambling, shopping sprees, spending money on toys, flirting with coworkers?
Do they approve of weekly date nights or do they like to do more spontaneous trips? What do they view as a healthy conversation? Cell phones off or on at dinner?
These things seem minute or maybe awkward to discuss; but trust me, they become very important when the romance spell starts to wear thin.

             Remember, you are dealing with another fully formed human being, with their own viewpoints, desires, likes and dislikes. This is the most thrilling and beautiful thing I can imagine having in my life. Understand creates synergy, and you must have synergy to function well.
The biggest thing for compatibility and chemistry is life goals. What do they see as the Ultimate Future? Does it differ form yours? Does it excite you, thrill you, do they give you energy when they are around you, or leave you feeling drained and overwhelmed?
All this things sometimes come in the first 48 hours when you meet someone, like it happened with me and my fiancé. My beloved seemed to be delivered in such a stunning, exciting way, it was obvious from the voice whispered inside to me of “That’s Him” that I had found my mate.

3.5 years and a marriage acceptance later, we are still madly in love and madly in Good Chemistry.

Look for the energy, the way you feel around them, and how much your energy influences them.
Then let the magic evolve naturally as you communicate on life, your past, your future, and with your bodies.

Cheers all the best.
