Why does it always have to be younger and more attractive?

I have read many posts on here and always wonder why one of the big reasons given for getting out a bad marriage is to find someone younger and more attractive to spend your new life with. Why are we not suggesting that the people find a more suitable mate that shares their values, morals, beliefs, and views for a marriage and the future, instead of just casing it on age and looks (all of which will change, it is inevitable). It is always thrown out as a suggestion to find someone younger and prettier, when it should be just someone better suited to them and their lifestyle. Not all of us are young and pretty/ handsome, so does that mean if we leave our marriage there is no one for us other than someone older and uglier that is just leaving their marriage and looking for us (the younger version of their just divorced spouse)?? :scratchhead:
