The husband and wife's age should be different. The boyfriend and girlfriend's age should be different. But why their age should be different? Did you ever think of that? If no we need to think why husband and wife age should be different.
Usually, the husband should be older than wives. Many prefer the husband should be more than 5 years older than the wife. I too prefer that. But why we prefer that age difference. There are many advantages to having that age difference.
A husband who is older than you care you better than a husband who is the same age as you. A husband who is younger than you will even do worse to you. Older husband is always good than a younger one. We can't say older husbands are better. There might be some exceptions because there is always a black sheep among a flock of sleep. The sometimes younger one will be a better choice. It is always in our hands to select among good and choose the best one.
Another reason why a girl should go for older men is because of the following reason. Women give birth and get much older than men. If you have the same age husband or younger husband, there is every chance he will go with other younger girls. The old man will never leave you because he loves you dearly. He loves you because you are younger than him. The old man will never be possessive because he is afraid of losing you. However, you should not take all those advantages of old man. There is one point where an old man gets saturated and will blast you badly.
My take on the above points. I also prefer a girl who is much younger than me just because of the above reason. However, I am not saying I will neglect the older girls. If fate has governed us, I will go for any girl irrespective of age.
May I hear your opinion too. Will you marry an older girl than you or a younger girl than you.
