How to accept that it’s over?

I think it ended a week ago because he told me to not contact him. I feel like texting and asking for closure but I know he’ll be rude and say things to hurt me. I’m not able to accept that it’s over or even to think about it. I still keep hoping he will reach out and maybe will want to talk things out. I want to start accepting that it’s over because somewhere I’m feeling that it really is. I’m not able to do anything, I’m just stuck on loop thinking about the fights, conversations, potential I wanted and the good times. I want to break this cycle and start to accept it, my friend who was following him on his socials told that he deleted all my comments on his posts. So yeah I don’t think he’ll be reaching out
