Did you ever wonder why?

Well, it is a kind of way to seal the deal. You're mine and I'm yours, and that's how it's going to be, basically. It's too bad a lot of people are divorcing these days, though. But it's nice to have something to celebrate with your family and friends.

after marriage only the life will complete

I've been married before, and at the time, my primary reasoning to do it wasn't because I was in love with my husband, but because I wanted to change my surname to his, so that he and I would have the same surname as our son. Our parents, due to religious preferences, wanted to see us married as well. And because of that upbringing we had, it was the apparent "right thing to do". Five and a half years and three more sons later we got divorced. If I were to remarry, my reasons to do so would be more about showing my new husband just one more way I am willing to commit to him, before a justice of the peace, or the "eyes of God", and/or before friends and family. But to me, it's mostly just a piece of paper, and exchange of a couple of rings, and a possible name change. Most of those things you can do without the need to be legally wed anyways.

When I got married I thought it would last it did not it only last for 5 years it was over.I was disappointed I had a daughter to raise by myself it was hard... cd

I've been married twice and wonder the same way as you do. One time, I did it because I was pregnant and wanted my child to have it's mom and dad, together. It was a helluva marriage and I ended it when the child was 10. Other than that, maybe people do it because it's a "man-made" law or thing that gives them leverage should their partner die? Maybe some do it for love... I can't figure out why, though!

I always ask this and can not find an answer. Actually, there are several: for money, love, the boredom, because need. But i think it`s boring to marry.

well.. you get married to seal your love with each other, in front of the witnesses, and your God (for different religions). i just hope you're talking about religious weddings and not fixed or cultural marriages.. hehehe..
