Believe me, I used to fight that way too. I think it came from growing up with brothers. I always had to find ways to hurt them that didn't involve strength. He shouldn't be talking to you that way either. Perhaps at a happier time you two could discuss taking the personal attacks out of the arguments. It will entail identifying what constitutes a personal attack and making both people aware of them. I'll bet if you wrote these lovely things you say to each other down in a list, you both would admit that they are not at all true, and perhaps even laugh at them.
