Vic, good for you, and I hope you'll continue to be very happy together.
I would worry about someone of 16 being married to a much older person, since their outlook will probably have changed considerably by the time they're 26, but once you're an adult, age doesn't matter at all. Once you're grown up, you're grown up. Nature is cruel because with age, people change on the outside, but they don't change on the inside. Society has pre-conceived ideas about older people, which is sad, because I know people who are 60, 70 and 80 years old but only about 25 on the inside, so society really doesn't know them at all.
If the woman is much older than the man, then perhaps children will be out of the question, but if the couple can live with that, I can't see why it should bother anyone else.
If the age gap is large, then there might be minor cultural differences of opinion - perhaps tastes in music, for example, won't be the same - but that could be the case for any couple of any age.
Louisa is right when she says it's other people that cause problems. It takes a great deal of courage to go against convention and marry someone whose age differs greatly from your own, but in my opinion, anyone, especially a young man, who has the courage to do what he wants to do really is a mature man with a strong character and with a mind of his own - and I applaud him.
By the way, I don't think Michael Douglas and Catherine are a couple in a million - marriages between young women and older men have always happened - and marriages between young men and older women are becoming increasingly common.
Did you ask this question for a particular reason, feist?
