How to get over someone quickly?

What are some tips? It’s taking everything in me not to text him. Ik he doesn’t care at all but Im still holding out hope he’ll miss me or something and try and come back. I can’t do it to myself. I hate it. I keep telling myself he doesn’t care but apart of me keeps thinking well what if he does? And it’s so dumb cause if he didn’t my silence would have made him reach out. Somebody help?
