Postmodern relationships

is exactly that. 

Marriage - is an attempt of a couple to forge and seal a relationship together. 

Divorce - this happens when marriage does not work. And last I heard it's about 50% of the time that this may happen. So it's a fair bet. I often blame it on a few things, but primarily on longer lifespans...humans used to have shorter lifespans, hence it's easier to stay loyal. Lifespans are extended, many of us are fortunate to live in safer environments, so the need to bind together is reduced. And all that + a little lack of love + a dash of curiosity of another individual...we get a fine recipe for a divorce. 

Postmodern relationships are undefined. In my opinion these are relationships between individuals..it could be complicated but it could also be very simple. Postmodern relationships are not standardized; couples who engage in postmodern relationships are not categorized in a generic mould but are defined by the lack of a structure. 

Postmodern relationships do not spring from a cultural need; nor are they built on function - these relationships, at the core, are often built on a continued interest in an individual over a period of time. 

More on this topic later. Gotta get a nap.
