Jealousy, Possessiveness,Untrusting, are all negative emotions of love.
Cowards that cannot face reality about themselves usually hide behind these words to show their love.The insecurity and selfishness that R.K. has will never let him know or understand the real meaning of Love.His inferiority is constantly shown when he opens his mouth and spews his garbage about how he is changed.Being underhanded and duplicitous is his inherent nature.MB will in her own time will also figure this out. Till then this marriage is going to be on shaky ground. Pity poor MB !!
