When an older guy seeks out a younger woman it's usually because he is looking for that younger woman to make him feel better about himself
moreover
older men pursue younger women is because they have a distorted view of women and relationships. Many of these men have been burned and as a result they tend to believe that all women in that age demographic are the same.
The sad part is that at one time most of these men did believe in love and commitment.
But after experiencing relationship hell and having their hearts broken (yes, ladies, men do get have their hearts broken
, they just won't admit it to you), many men make a decision to avoid the older women.
