Since half of marriages end in divorce it seems fair to ask if people should commit to someone "forever."
Marraige and love consists of layers and things could be examined within. Things like open relationships and seperating sex from love gives some relationships options, but they still return us to the main question (Are we meant to be with one person forever).
What is your opinion on life-long monogamy and/or the purpose of marraige?
Marriage is when a couple plans on having children. Otherwise should live together.
Like MANY things, I feel this is a very subjective issue. Some people are very happy with one person forever. Some people are only happy with one new person per month/week/day.
It's an individual choice and preference. Biologically speaking, I don't think a case can be made for one or the other with absolute certainty.
Ethically/morally speaking, same thing.
I think you pretty much sued it up!
