I think women start most relationship fights...?

I am convinced that women are the cause of most fights in relationships. Look at the differences between men and women. In friendships between men, there are almost never fights. On very, VERY rare occasions, men will get into squabbles. But generally they make up within 5 minutes and they are back to being best friends. Friendships between women are totally different. Girls will get into these huge pissy fights and squabble over the smallest things. I knew these 2 girls who had been best friends with eachother since grade school. In highschool, one of the girls dated a guy the other girl didn't like. They squabbled with eachother for months and now they absolutely hate eachother. It's been 2 years now and they still haven't made up. I am conviced by seeing these kind of squabbles between women that women are the causes of most fights in relationships.
