How can I just move on?

[Heartbroken2000]

How can I stop feeling lonely, sad and single after getting left by a guy I wasn’t even in a relationship with? We just did things that couples usually would do in a committed relationship. Will he come back?

Focus on other guys and don't spend to much time alone. And do not wait for him to come back.

Pray to God through Jesus Christ. Ask God to heal your heart.
And don't look at the guy's social media, and block his numbers and accounts online and do not talk to him ever again.

Talk with other guys to keep your mind off of him.
