Everyone should just ignore him. He's trying to manipulate people into sympathy with the hope of guilttripping you back into the relationship. I read no real self-reflection, only how much of a victim he is in this situation and you're the offender since you "always pick a fight because you misunderstand him".

This behaviour is just so toxic overall... leave him and never look back, he has some serious issues to overcome and since you're not his therapist, you're not responsible.
