Most people with failed or failing marriages simply DO NOT KNOW HOW to make it work! Even counselors can be ignorant about making a marriage work well. My wife and I studied a few marriage skills teachers like Barbara DeAngelis and Relationship Skills [google them] and seriously began USING the things they teach. We've been together for 22 blissful, trouble free years now thanks to just a few powerful relationship tips and methods. It amazes me how few people we know use anything like we learned like 100% honesty and truthfulness ALL THE TIME - not just when it will get us something, NO criticism EVER, frequent affection with NO hidden agenda, the 20 second kiss, treating each other exactly the way we did on our first date ALL THE TIME, being consistently kind, loving, respectful, good, fair, empathetic, empathetic, loyal and BEST FRIENDS - ALL THE TIME - just like our wedding vows say!!!
Others may find us "boring" because we do not tease each other or FIGHT but our happiness is more important to us than trying to be "exciting" to very stupid others. We have outlasted the relationships of almost everyone we know who were not "boring" but they also FAILED!

good luck learning how to make it work,
