Any one who has been in a long relationship knows that sometimes you can find it hard going. But relationships that have been good are usually worth fighting for. Of course, at the end of the day, only you can decide whether you want to put the effort in and fight for something that has been valuable to you. The third edition of the what has become a classic on marriage enhancement and divorce prevention,"Fighting for Your Marriage", features the latest research and changes in culture in our society. New and revised, Fighting for Your Marriage , is based on the widely acclaimed PREP (Prevention and Relationship Enhancement Program) approach. Groundbreaking studies have found that couples can use the strategies of this approach to handle conflict more constructively, protect their happiness, and reduce the odds of breaking up.
