I've learned that when the arguing gets to the point where it overtakes everything that it's time for a "time out". Either or or he leaves for a while...it isn't anything bad and no one gets offended and there isn't any fighting about it...one or the other just leaves until we cool off. It's healthy and mature and it always works. If we cannot decide who's leaving then one of us gets into our car and just leaves. We don't do it to hurt one another...we don't go in search of affection from another or to friends to tell them we are fighting...we just go somewhere and chill...whether that be the mall or out to eat or even out for a drink by yourself. Sometimes I'll go to Starbucks or Barnes and Nobels.
When we are feeling better one or the other will call and we go home. It works. After a while you will start feeling secure with out one of you leaving and you know that there isn't any cheating or anything bad going on...you are doing it to keep the drama and insanity out of your relationship and so that things that shouldn't be said won't be said in anger. It will take less time "away" and you'll realize how silly your fights are and you'll actually start to miss one another sooner. It's been working for us for years.
Peace, Love & Happiness
