How can I forget someone?

It is not easy to forget someone. You can divert your thoughts from him by diverting your attention. For example, play with friends, do things that make you happy, watch comedies and relax yourself.

I also make myself very busy and full every day. It's best not to meet him, and not to get in touch with people who are related to him. You'd better make some new friends and let new people take his place.

You don't have to think about how to forget him, because the more you want to forget, the more you miss him and the more you can't forget him. Never forget someone deliberately, because then you will remember him more deeply than before. You just need to give time to solve your forgetting about him. After a long time, you forget.
