When an older man marries a younger woman people hardly notice or comment. However, when an older woman marries a younger man there is lots of conversation. Many times these relationships work out and the couple live a happy and productive life together. And, many times these relationships do not work out.
There are many couples with an age difference, and very often men select an older woman because he feels comfort in the relationship. Very often these women do not even look young for their age. When a 30 year old many marries a 40 year old woman she still is looking pretty good, if she has taken care of herself. However, as the years go on the age gap becomes more apparent. This is not necessarily a bad thing. Women do tend to live longer so this could sometimes even that gap. If a man does not want children he can marry a woman past the child-bearing age. Very often couples who have had one marriage and children are grown can meet and fall in love, regardless of the age disparity.
Some marriages with big age differences are doomed from the beginning. Demi Moore got 6 years with Ashton Kutcher. However, it was inevitable that a hunky 30 year old guy is going to notice the 20 something beauties, and take advantage of easy situations. Moore is headed pretty close to 50, and though she looks outrageously gorgeous–maybe not first thing in the morning.
Age is not always the major factor for relationships coming to an end. There are many factors involved. However, as years go on problems to seem to appear. Relationships where both are close in age can be special…since you have always danced to the same music.
