Posting this on behalf of a friend as I'm not sure how to help her. To get straight to the point, her partner gets defensive very easily. She could say something that's not even aimed at him or something that hasn't involved him and he will immediately get defensive about it and say "well it's not my fault". It's starting to get on her nerves but she's trying to be understanding, he was in an abusive and controlling relationship before he met my friend. Any advice?
