How do you get over a narcissist?

Finally ended things with the narcissist for the last time. How do I get over him? What can I do to let go and move on? Last time I reached out in a moment of weakness and I don't want to do that again. I don't know where to start other than blocking him (which I will do tomorrow 🤞🏾). Any tips would help!

Edit: guys I need tips other than blocking cause I will 100% block him haha but I'm just wondering what else would help in moving on.

Edit: guys dont attack me. I understand and I will block him. I'm doing it tomorrow because I need to do something first before blocking him. 🤦🏾‍♀️
