Open your door to these new possibilities and see whether a few suggestions might help turn your marriage around. There is, of course, no foolproof guarantee that you will be able to turn your marriage around.
Every marriage is different, and there is certainly no quick fix for turning around a marriage.
It is also very important to remember that while some advice might work for one marriage, it might not work for another marriage. A marriage, like any relationship, can act like a life of its own. For this reason, every marriage has its own characteristics, personality, etc. First and foremost, if you are in any kind of abusive situation, seek professional help immediately. You can contact a counselor, psychiatrist, psychologist, or any other kind of trained therapist or relationship expert.
