your preference - marriage or live in relationship?

I would say thats its better to live with somebody and get to know them properly before you move on to critcial stages such as marriages etc. In a relationship its ideal to take 1-2years out to get to know your partner and when you are sure that the relationship has a strong base and that you can build upon it thats when the time would be right to propose to your partner. Getting to know and understand the other person is the key to a successful relationship/marriage.

i prefer live in relationship

I think it is better to get married. Absolutely livingwith somebody is a waste of time. There is a fear of commitment and that is a big sign of insecurity. People like this usually don't know what to do with their lives.
