Fuck him and move on with your life. You are young, enjoy your life. Travel do things see the world!!! Don’t get all hemmed up behind this one guy, you will meet plenty of people. You were in love give yourself time to heal. It takes time to get over things. He is young and still trying to figure things out, don’t put so much pressure on yourself to have relationships. The time will come in your life for all of that. Enjoy life.
