What is wrong with this guy?

I met this guy back in 2019 through mutual friends that I have known since highschool. We hooked up in the past and fast forward to today, he still hits me up. He will randomly block me, unblock me, block again. He also will give me attitude if i don’t answer his messages and he spams me. Im not interested and I have given countless signs with my responses. I told him to quit hitting me up when its convenient for him and that I don’t talk to people who give me attitude.
