What a wonderful thought to ponder. Marraige is the ultimate level in a relationship and should not be consider likely as girlfriend-boyfriend relationship. I believe If such matter occurs then it should be one of the tests, that both husband and wife should learn how to manage well. Consider the factors - before it happen, when it happens and the consequences after.. after. Mistake can not be corrected by another mistake - separation or divorce is never a solution to a relationship founded with love and commitment.
