I have noticed that a lot of the time when a man or woman gets with a partner that is more attractive then them, or out of their league in other words, the relationship pretty much always ends up with someone cheating (with the less attractive individual usually being the one who cheats).

I really do believe that there is a much better chance of having a successful relationship by being with someone who is at a similar level of physical attractiveness to you. The insecurity that comes with a imbalanced relationship in terms of looks, or the inflated ego that develops from being able to bag a very attractive partner, has a greater chance of propelling the less attractive partner to cheat.

Has anyone else noticed a similar pattern?
