Hehe, Leo boys are a bit chauvinistic, but in fact, they really care about you and want to protect you all the time, so they have to show their strong side, which often hurts their loved ones by mistake. Don't be angry with him.
First of all, he will not admit his mistakes. Secondly, it will make him feel a little disappointed. Tell him your feelings gently. Maybe he will still not listen to your advice, but don't worry, as long as you say it, he will definitely care and will try his best to restrain himself.
Hehe, you can give him a small gift on a certain day, take the opportunity to tell him your thoughts, he will be happy, and he won't dare to yell at you anymore. Customize a military license plate or something like that with engraved words for him, which will tie him up well. Hehe, come on.
