If we accept TRP's definition of hypergamy and not the dictionary's definition, then hypergamy basically means : looking for the best possible partner.

If that is true then aren't men hypergamous too when it comes to commitment (since they're the gatekeepers of commitment themselves)? Of course most men will have sex with anyone because of polygyny , but when it comes to having a committed relationship , don't they basically look for the best possible partner , the most attractive one ?

What about the fact that some high quality men abandon their wives for their 20 years old mistresses ?
