Ex boyfriend disrespecting me?

I told my boyfriend to stop talking to me because he was not treating me properly. He wouldn't agree to it and each time I asked him that if he wants me to leave his life, I will, he either remained silent, or said he has no opinion on this or that he will talk when he wants to.

We argued again and he finally agreed that he won't speak to me. However, he did not follow through it and kept saying hello, how are you.

Even after we decided never to speak to each other again.

Is this disrespectful that he does not respect my decision?

We broke up once and this is how he reacted I told him to stop talking to me because he was not treating me properly. He wouldn't agree to it and each time I asked him that if he wants me to leave his life, I will, he either remained silent, or said he has no opinion on this or that he will talk when he wants to.

When I tried to cut him off he wouldn't accept it and became upset and sad. He wouldn't stop talking to me and would constantly say hello and look distraught with our fall out. Even after meeting her, he would keep staring at me , and then when I took him back, he became happy and normal. Otherwise he couldn't sit and study and would keep looking back at me while leaving.

Why do so much drama if he doesn't like me, doesn't want friendship and doesn't come to see me?
