Bole So Nihaal Sat Sri Akaal!!!  

no, marriage is part of grihast jeevan, life of a householder. Please can have sex in their boyfriend-girlfriend relationships if they want to to be honest. Why did you bring this up anyway? I am just saying you mentioned marriages with expiration dates, and muslims do indeed have these available!

Most western kids go into nursery early on, then pre school , then primary and so on  . In terms of active hours put in parents have less and less contact with their kids these days. So if kids are beta or not you can't just put it at the door of how the mum was

I'd recommend you read a book like 'a new earth' by Eckhart tolle. The corruption you speak of is just a manifestation of 'ego' (haumai), the me/mine . Ever tried to get a toy off a kid? They will act in a conniving way to keep it (my toy and all that). This then just manifests in different ways as people get older and have different types of 'my toy'. Ego is the disease , the things like corruption are just the symptoms 

So for you marriage is lifetime insurance of guaranteed sex.
