There have been many studies on the subject, and it seems that most people have a pretty good idea how attractive they are relative to others. Most people naturally begin and maintain romantic relationships with others who are similar in levels of physical attractiveness. When partners are mismatched in this regard, their relationships tend to be shorter. Women who said they are significantly more attractive than their partners are likely to feel lower levels of commitment to the relationship and are more likely to flirt with other potential partners.
On the other side, the less attractive member of a mismatched couple might be more susceptible to feelings of jealousy, which can be detrimental to relationship health. People who were friends with one another prior to getting romantic are less prone to the downfalls of attractiveness disparity. One study found that longer periods of acquaintance make relative attractiveness less important.
The end of a marriage is a stressful and trying process for many people regardless of why they are divorcing. There are a lot of legal issues to consider, including property division and parenting time, and an attorney can often assist in the negotiation of an agreement that addresses them.
