A bifurification of a marriage is similar to an annulment. The marriage will be dissolved quickly over a financial crisis with one of the parties. It is very subjective as to whether this is a good or bad practice.
I totaly feel bad, they had a good marriage.
It is netiher bad nor good. However, it appears to be less and less popular.
Same-sex marriage is good for the same reason marriage is good. It promotes monogamy and the stability of families. It doesn't cease to be good just because of the gender of the persons involved.
at last the couple will have a bad future
It is neither good or bad.
early marriage
I don't think this is a question that anyone can answer but the people who are getting married. It is an opinion on what is considered "early". If you feel you are ready to get married then by all means get married.
Giving good education to the teens by the parents can help in preventing early marriages to the youth nowadays.
no one ever knows, but my guess will be not a good one.
Early marriage also causes those people to have children early
It's not bad, as far as I am aware. Marriage is a good thing that benefits both partners. Denying a minority the right to marry because of someone else's religious beliefs is very bad.
