I mean if u love him you love him, that's the end of the story. Have a proper conversation with him and let him know how you truly feel. If he says that he wants to get back together, that's cool. But if not then just stop. Don't and I mean don't look desperate and just focus on yourself and in your education. Remember when talking to him about how you feel be clear but don't seem desperate.
Let us live, for we must die.
