Maybe you maybe sit down with the woman and have a discussion before something *does* happen. You have a daughter, and that is important to keeping you two together. However, if you sometimes get so full of rage that you feel you may hit your girl, you may want to stalk off and take out that anger on something else. ( You probably already do.) I don't know what kind of girl you're with, but I know that children can sense tension between parents. If it doesn't happen a lot, then it's just going to have to be you gritting your teeth and dealing with her shit. Maybe also, it's just that you get so mad that you feel like you may pop her one, but you know deep down that you wouldn't. It's just that she gets so aggravating that you imagine it happening.
