Recent research shows that couples break up because they do not know how to resolve their differences through communication. Hostility only breeds more hostility. Venting the negative emotions may clear the air temporarily, but it does not solve the underlying problem and serves to make it worse. Backing away from the conflict and ignoring it only sends each partner into secretiveness, withdraw and isolation. The message becomes clear--the couple that fights together stays together happily only if they use the techniques of conflict resolution.
