How to deal with a manipulative, bread crumbing guy?

Honestly, I’ve tried once to politely voice my opinions, but he only started defending himself and got mad. I even told him I’m not feeling well so I won’t be communicating much and he wasn’t understanding at all! I suspect he won’t change and I have to protect my peace and energy, so I limit contact with him on my side. I don’t reach out first, and if he does send a message then I don’t reply right away and sometimes I don’t reply at all. He’s getting mad for that as well lol. What to do now?
