What does it mean when a man keeps trying to come back even if he was rejected?

My ex who hurt me plenty, keeps trying to come back into my life. I mean.. we hurt eachother in the past. We were both stubborn and immature. We broke up 6 years ago. During these years he kept on trying to talk with me. He was talking with the walls. This year we reconnected. Right now I am sceptical and cold every single time he reaches out. I still have strong feelings for him but I wouldn't jump into his arms blindly. I reject him but in the same time I tell him I still care. I reject him but I let him hug me. I reject him but I would say Yes, let's try this again but instead I say: NO. A few days ago he blocked me and wished me a good life. He said that I m not good for his mental health. That he can't be just friends with me and that's why he prefers to back off forever. Overall he is showing me that he is selfish, right? He has no patience for us to work it out slowly. Am I right or am I not?
So do you think he was serious? He just blocked and he will move on? Never again reach back? Please, your honest opinions!!
