Though I was little late in taking final decision for marrying a girl, but , yes, definitely, it is the best thing ever happened to me. Alhamdulillha. I am really happy with my better half.

One thing:

It can also be defined as a relationship between people of the same sex.

This is not the marriage and it is against nature and Almighty's rules. I do not and will never accept same sex marriage.

Your very next sentence void this definition of same sex marriage.

Fruitfulness-The first purpose of wedding is fruitfulness, that is to multiply. This entails two people becoming three, four, five etc.

Exactly, how the same sex married couple multiply?

By the way, really wonderful post on marriage. Keep up the good work buddy.
