You guys are mean. This was a serious question written by someone who is trying to learn English. Straighten up now and answer the question seriously.
I think it's sad when love does not succeed. People need to be friends with a lot of other people before thinking about marriage.
Here in the USA young people wait a long time, now until they are between 25 year old for women and 27 years old for men. They have many (more than five) sexual partners before marrying. It seems to be working. Our divorce rate has been in steady decline since the 1980s.
Marriage, whenever anyone or wherever anyone, engages in it, it is a serious prospect, a life changing experience.
