When me and my BF first started arguing, I had a bad tendency get really quiet and just agree with what he was saying and keep saying "yes, I'm sorry" "I was wrong" "I'm sorry" "You're right" over and over again. I hate getting in arguments and at the time, pacifying him seemed like the thing to do. It actually made it worse and he'd hate it when I'd do that. I found that it was better when we both gave our points, made our arguments, and then decided we could reach middle grounds or else decide that we were indifferent about it and then leave it alone. When you're arguing with him, act as though you're interested and that you'd like to know why he disagrees with you. When both parties do this, your opinions are validated and less emotion is involved in the argument.
