Easily solved with marriage counseling and/or reading "The Love Dare" or "Proper Care and Feeding of Husbands" or some of those type of books that lots of ladies on here love.
Divorce is never the EASY answer. Your problems follow you. Your kids learn that when the going gets tough, the weak bail. You just need to learn to fight fair. You guys can do it. It only has to start with one of you learning to be nice and then the other will follow.
Just wanted to add I studied this very thing on a college level course Child Development class. It is a myth that fighting, even being jerks like you guys are being in the middle of a heated fight, is a good reason for divorce. I can show you 2 inches thick of page after page of psychologists, psychiatrists, doctors, family therapists etc that have all come to the conclusion that divorce PERMANENTLY hurts your kids. Dirty fighting hurts them, but not anywhere near as severely as breaking apart their family. Not even close. Please go with the research.
By the way, I am not a smug, holier than thou person. I am a child of divorce, my husband and I have nearly divorced millions of times, I have worked my butt off to stay married and I was not saying that people who divorce are bailing, but SOME of them are. Did I name anyone specifically? This poster is not with an addict, an adulterer, or a wife beater. I would never tell someone that they had to put up with that. To clarify, kids learn conflict resolution from their parents. My parents never learned to resolve their conflicts with each other and eventually divorced. If a kid sees a parent LEARN conflict resolution or peace-keeping skills, then they learn that for their own life. I have had the hardest time in my own marriage because I went in not knowing how to resolve anything. Every big fight we have had, I have always had the urge to bail. I had no good role models to follow. All kids need their parents to be good role models. I believe, based on your post, that you can do it. You and your husband love each other and you said you don't fight a lot. Also that there was no violence. That's great! Be strong and learn how to do this. You are always better than you think.
