The reason is not only bcos of physical relationship, also bcos of Mental relationship. I do not want to blame on the young couples alone,to be shared by their respective parents also. My friend got married recently and now they are in Bangalore court for divorce. Both are from IT. Whatever the job we do, at the centre, the elders should talk about what is life, love, affection, give and take policy, but for the generation who re in courts, the elders told only about Money, Career, USA, Australia and London. Nothing else. My friend's wife siply told him on the third day o their family life that, u have canteen in ur office and I have in my office and so let us have our Breakfast and lunch there, dinner we will have at any restaurants on the way. Weekends pacca outside...People in this forum will call me as anything, but the fact is different.
In the end, I would like to say one thing, Iam a HR Guy in a software company and married to a software engineer, currently in UK for for a project.
