Do you believe in divorce simply because "you are not happy"..no cheating or lying or anything like that..or do you believe you should stick it out because of the commitment you made?

Clearly this is something each person has to decide for themselves, but I think that the promises made going in to a marriage are primarily of value to helping people make it through rough patches together... specific periods when they are having difficulty working out differences, or the marriage is under strain from the circumstances, etc. I think if two people are really just growing far apart over a long term, and it's not a matter of needing extra strength to work through problems, then a wise person really does have to ask "did I just make a massive mistake?". Life is too short, and it happens. To stay together forever with someone who is just not compatible, simply to justify your original promise, is not coherent with the deeper levels of personal integrity and responsibility. That's making the original promise more real and powerful than your living and well-considered good judgment.
