The success rate depends on the input of the love and commitment, all the communications. Men are usually loyal in marriage, and women. As for my advice: Do not love the successful marriage of the girl cause more than the parents who always think they are in reality not TRUE. The second is religion. Girls will drag your life, make it more tragic. Third: forgot to love and marriage, career-oriented there is no such thing, because it is pure love ILL logic. Arranged marriages: depends on who is making arrangements, arrangements or if they are mentally. It sounds to leave their line of law but believe me it's ABSOLUTELY true.
