the trouble with any alternate lifestyle is that it is never broadly accepted in our society,simply becos our society is so diverse. I am sure that live in relationships are common in the more affluent sections.This will always be met with sceptisicism outhside their circle...so it places an unnecessary burden on the couple..also many women are earning quite well and hence do not feel the need to settle down early....but would still yearn for physical companionship. Ditto with men...the one marriage one partner stereotype is endlessly potrayed as the ideal...no doubt it may be the ideal scenario...but as we all know life is far from ideal!
