Here are some steps you can take to forget a guy:

1. Give yourself time to get over him. Admit that you need some time to be on your own, to think about what happened, and to deal with your emotions. The sooner you do this, the sooner you’ll be able to move on.

2. Focus on the bad qualities when you think of him. When you’re trying to forget a guy, it’s easy to romanticize the relationship and remember only the good times. Instead, focus on his bad qualities when you think of him, like the fact that he cheated on you or didn’t pay attention to your needs. This will help you remember why you’re no longer together.

3. Remember why you’re not with him anymore. When you’re trying to forget a guy, it’s important to remember why you broke up in the first place. This will help you stay strong and resist the temptation to contact him.

4. Cut off contact with him as much as possible. Talking to him will only make it harder to move on. Unfriend the person on all your social media accounts.

5. Let the person know you need a long break from them, even if you want to be friends in the future.

I hope this helps! Let me know if there's anything else I can help with.
