Would he even miss me?

A guy (25) pursued me (23) for 6 months long distance, and while we never dated we both were really into each other. He ended things with me to pursue a relationship with a 19 year old at his college and I just can’t stop telling myself he probably doesn’t miss me. Is there any advice I could have on how to stop these bad thoughts?

Thank y’all in advance 💗
