Dating 23 year age difference
A 2003 AARP study reported that 34% of women over 39 years old were dating younger men.The rational choice model suggests that people look for partners who can provide for them in their life (bread-winners); as men traditionally earn more as they get older, women will therefore prefer older men.Parental Investment Theory refers to the value that is placed on a potential mate based on reproductive potential and reproductive investment.The theory predicts that preferred mate choices have evolved to focus on reproductive potential and reproductive investment of members of the opposite sex.Thus, both sexes will have to compete and be selective in mate choices.These two theories explain why natural and sexual selection acts slightly differently on the two sexes so that they display different preferences.Dunn concluded that "Not once across all ages and countries ...did females show a preference for males significantly younger than male preferences for females" and that there was a "consistent cross-cultural preference by women for at least same-age or significantly older men".
In August 2010, Michael Dunn of the University of Wales Institute, Cardiff completed and released the results of a study on age disparity in dating.

There are also social theories for age differences in relationships as well as suggested reasons for 'alternative' age-hypogamous relationships.
Age-disparity relationships have been documented for most of recorded history and have been regarded with a wide range of attitudes dependent on sociocultural norms and legal systems. Relationships with age disparity of all kinds have been observed with both men and women as the older or younger partner.
It states that one should never date anyone under half their age plus seven years. Therefore, according to the above rule, this potential relationship is not so adequate.
