"love like chemistry, it mixed and its break"

what type of bonding between man & woman??

"double bond" - once they're bond together & can't move freely?

or

"Single bonding" - tie each others but easily affect by other elements?
_____________________________________________________

Between which individual that the double bond will occur?
In what kind of situation?
Do we need to add in any solution?
Is it takes time to prove that the double bond is stable as ever?


Will the single bond turns into double bond?
What types of solution do we need?
What kind of situation, presure or temperature do we need?
