You're killing me. A moment ago I wondered how you can NOT be a romantic with a post name like that. Now I see what a good thing it is that you aren't a hopeless romantic. If you were, you might be tempted to unsheath your sword and fall upon it so you could indeed disappear and make the dreams of your fair damzel come true.
BrokenTree,
SirPrizeMe gave you some pretty good advice. Find a way to avoid the fights with your W, if only for the sake of the children. the are watching and learning from the two of you and very soon some of the behaviors you and your wife are displaying will come back to you. One day you will no doubt hear one of your children use the EXACT same tone of voice and snippy remark you will immediately recognize as one you or your W has used. Children are natural born mimics. If it continues it will become a part of their personality.
