Sounds good. I'd be happy to help. Just remember, the heat of argument is the worst time to bring things up. It's best to agree to a time when you are both relaxed to talk. And it's good to start by saying something nice, like "I appreciate that you did ____, (cooked a meal, watched the kids, bought the food you like, called your parents, went somewhere with you without complaining, etc.) Breaking the ice with a compliment sets the stage for a more receptive conversation.
Then try to make a problem statement without any accusation. Such as, "I think we need to be careful with the things we say to each other when we argue." See, no accusing there. Then see what he says. Always give him a chance to add to the conversation. Once you have laid out the problem, you can either define it further, such as both of you saying what kinds of hurtful things you think should be avoided. His ideas might be different than yours, so you do want to listen to what he says. Maybe have pen and paper ready to make a list with no emotion attached. Make sure that his ideas are written down as much as yours are.
Then you want to discuss solutions. Some possibilities -- no name calling, or saying "always", "never", try to avoid cursing, stick to the subject, etc. Maybe agree on a sign that either of you can do when one person crosses the line, something like a raised fist, or another easy to see physical sign. And agree that when that sign is shown, the argument stops right then. Remember your kids are learning how to conduct adult relationships by watching and listening to you. Do you want them to say these things to their spouses? anyway, when the talk is finished, kiss each other. Yes, kiss. At least hug.
