Relationship of nowadays is not built based on genuine love but what they stand to gain in the relationship which is why if that reason goes off it becomes very difficult to still remain committed to that relationship anymore. With or without the presence of money the love of parents still remains but can never be so in that of boyfriends and girlfriend.
Talking about options, I don't think its because they have options while parents do not but because parents has genuine love for there children while that of husband and wife is optional.
Well said, the love of our parents is true definition unconditional love, more especially motherly love, the bond that exist between a child and mother is unmeasurable with anything, that is why when a child misbehaves, the father might be forming too hard or will I say difficult to aproach, but the mother always have this soft spot, the love of mother can not be compared to that of husband and wife I agree with you.
Without being told, we have heard to seen women mostly doing business with marriages, they pretend to love a man, which turns out to be fake, just because the man is rich, the ask for divorce in any little thing just to get some part of the man's wealth, talk more of when the persons that funds the relationship or marriage is no longer capable, going separate ways becomes too easy.
