Is marriage a dying instituition ?

There's a lot of adult who are not willing to be committed forever and be tie down to the person they're with. They have this fear of losing their "FREEDOM" and individualism. A lot prefer to the LIVE-In arrangements so that they'll be able to work things out any differences they would encounter. It's easy for live-in partners to get out of the relationship than getting an annulment or divorce. That's why many people are in to the LIVING IN state.

its bad when people not marry. for me, marriage still important to make sure more people will care about our future when old soon. it make need of responsibility more in their heart.

If we continue to propagate individualism yes there will be a time when there were will be fewer marriages. But I don't think that marriage is a dying institution. Love supersede all. You often find couples who have been living for some years than finally decide to get married. Perhaps this is bewildering. They are living together having grown up kids, so why marry late in life? The reason must lie because they want to consolidate their experience.
