Marital bliss

Marriages today are a hotbed of infidelity. I've seen enough marriages to realise that the way way to be happy in a marriage is by not expecting anything from your partner. Just yesterday I came to know of this couple...mid 40s, 2 grown up children...apparently they same in the same house but everything inside is seperate..seperate rooms, seperate utensils, everything...makes me wonder why they are even living together. The daughter had apparently run off and got married....again I wonder what made her believe in the institution of marriage...institution..as in mental institution. There are at least 5 other cases like this in the building where I stay...and in all I've noticed that women dont cry over broken relationships...even if their husbands are seeing someone else..the women just move on, do something worthwhile with their lives..they still need that institution for society but for all other purposes, they have no attachment to it. I think it's wonderful.
