A marriage takes WORK to be successful. Not all times will be as good as you would like. It is a LONG_TERM commitment that goes through many phases. If there are things you don't like, speak-up and work to make them better. Don't just get-up and leave. The 2nd time around isn't easier and I'm not sure that being alone is the answer either. The divorce rate just goes up for each consecutive marriage. It is not pretty. You just carry your problems from one relationship to the next if you don't work on fixing them.
My Thoughts: During the bomb/post bomb phase, The WORK required is different than the work required when the other person is also working on the R. Know the difference and apply the new learned behavior to improve the R.
