Marriages in Nigeria and most parts of Africa are sustained by women. You can argue this with your village deity. Women in general, put up with a lot of bullshit just to make their marriages work. From childhood they have been taught that a wise woman keeps her home. In order to keep their homes, they end up enduring a lot of ill-treatment.
Find any woman who has been with a man for donkey years and ask her if she would love to marry that same man over again in her next life. Majority would say no. This brings us to the point that most marriages are endurance marriages not happy marriages. Unfortunately, we are told that marital success is about duration.
A successful marriage isn't about duration but happiness. If two people spend five years together, happily and add immense value to each other; if they decide to break up without fighting about it, their marriage can be rated as successful. Spending eternity together in sorrow isn't the idea of success to me. It is what you do in the marriage that counts not how long.
