I think every situation is different and there is no right or wrong answer (except when dealing with minors and grooming very young people that is always wrong).
My husband is 12 years older than me, my sister in law she is 5 years older than her husband. Both of us are happy in our marriage. I have met couples with 20 years age gap too! As long as you are in a happy and healthy marriage I think age gaps are not so important.
Thank you for your honest comment. But I’ve seen some ladies turn down a man that is 20 year older than her, that she need someone that is like years older that her so she can properly respect her.
Yeah, I think everybody have their preferences as regard this matter.
