Good intuition, and now we have hard scientific data to support it:
Please note I am using a somewhat more general meaning of the word "happiness" than usually understood.
Also, in your statement I would replace "same manner" with "similar manner, opposite direction" or something like that.
I have read "Relaxation Response" a few years back (https://www.amazon.com/Relaxation-Response-Herbert-Benson/dp...) and shortly after have practiced this method every day for 6 weeks with my partner. We did this by listening to the meditation "Bring Mindfulness to Your Day" early in the morning and i recall this being a beautiful period of serenity for both of us. Highly recommend the meditation - her voice alone is incredibly calming, plus: it gave a good overview of different meditation techniques.
 This is the first track on Olivia Hoblitzelles meditation CD "Relaxing Mind and Body with the Benson-Henry Institute for Mind Body Medicine" which can be found here https://www.amazon.com/Relaxing-Mind-Benson-Henry-Institute-... and on itunes
