Hello,
I think in my own candid opinion, a man shoud be older than his wife with a maximum of 8years to a minimum of 4years,my reason,in relationships between a couple who have age difference of lets say 2 to 3years, u see they tend to think alike cos their age is just within the same bracket but when the gap is like i said above there is always a difference.i will like to use a friend of mine as example, she use to date a guy who was just 3years older than she is, u see,they reason alike and do things people within that age does but presently,her fiance is 8years older than she is and from what she is saying she has never enjoyed any relationship the way she is now.
Another reason is that women tend to look older than men becos of the fact that once they start having kids, their looks change,so it is advisable for women to marry men who is their senior with atleast 8 to 4years.chao
