I think you can take the initiative to talk openly with each other. Speak your mind honestly. If the other person refuses to communicate with you, he will still ignore you even if you take the initiative to communicate with him. Then sometimes letting go is a better way of life. At least he didn't drag you down and waste your youth. You can find the one that suits you best. Regarding violence, don't try to change that person. Violence cannot be formed overnight. People who are prone to cold violence generally have some dark sides in their own growing environment. And these dark sides affect each other's physical and mental health.
Don't try to think that you are different from others and don't have a virgin mentality, thinking that you can influence each other. For different people, the information returned by the environment is not the essence of things, but only confirms the importance of communication. Two people should be honest with each other, solve problems through communication and strengthen their own construction, so that you can understand others well. In this case, there will be absolutely no cold violence.
