I feel that "age is only a number" and it doesn't matter what the age difference is between a couple. If they are happy with each other, who should care how many years apart they are in age. If something (God forbid) were to happen to my DH, if I ever started to date again I would be more concerned with what the guy was like in character, how he treated me and others in my family, etc. rather than if he was older or younger than me.
