I have done couples therapy since the seventies. Names and faces have changed,but the stages of successful and unsuccessful marriages have not. Stage one is the period the partners fall in love and commit to each other for a lifetime. This is generally an exciting and loving time where each finds the best in each other and each shows their best sides. Stage two is when each realizes the differences they have that cause friction and recognize the need to clearly define them and learn to compromise and overcome them. Stage three reflects how successful they have been in resolving their differences in a way their love matures and lasts a lifetime. If this does not occur,the relationship at best will be very difficult for each of them. At worst,the relationship will end in divorce with feelings of anger,rage,frustration,indifference,distrust,betrayal or some combination of them.
