It just serves a different purpose. 

Example:
I love women. 
My wife serves a different purpose than my girlfriend. 
My girlfriend serves a different purpose than my mistress. 
My mistress serves a different purpose than my secretary. 
My secretary serves a different purpose than my best friends wife. 

The women that are valuable to me doesn’t necessarily have to be valuable to my best friend. And that is ok. It is not a competition. 
(EVENTHoUgH his wife is smoking HoT!)
