What does it mean that your former good friend told you to take care of yourself because of contradictions? Do you want to identify with him?

It seems that you did something that upset him too much, and he doesn't seem to forgive you either. Explaining or apologizing at this time may be counterproductive. Give him a cold treatment, keep a distance for a while, and then find a suitable time to explain or apologize to him sincerely. If it's not convenient to talk in person, you can send a text message or something. If he still can't forgive you, it means that your fate is over. Relax. There are only a few friends who can accompany you for a lifetime. But good luck getting back together.
