If two people find they can no longer get along together they should divorce. Why stay married and be miserable together?
Yes, its easier to just quit when things get tough. We should definately be teaching our children that lesson.
I know of one young couple who married about two years ago. They seemed like the perfect couple, but after a year or so they began having constant arguments. Both became miserable to the extent of not being able to pay attention at work, and being constantly depressed. They are now separated and in the process of divorce. Both agreed to the divorce and both are much happier now and are getting their lives back to normal again separately. I don't know what the basic problem was but divorce seems to be the right answer. No children are involved.
Why should the state say no?
