Couple of Questions : First of surely, there must be a reason he dumped you, what did you do? What did you say? Perhaps he just lost interest in you and found someone else. Maybe he has school on his mind. The factors are nearly endless. Now secondly, why would you make him care, you just stated he is an 'asshole' , so why? It's obvious depending on the factors that he dumped you for a specific reason. Maybe you should talk to him about WHY he did what he did. There are a multitude of reasons. Thirdly, why should YOU care? if he's truly an asshole then just forget about him. Move on, If I were in your position, then give him the cold shoulder or cold stare. I don't know what girls do to make guys jealous. But whatever it is, initiate it if your gonna go after him. But i'd say forget about him.

You just said he's an ashore. Continue on with your life, show him you're great without him. Focus on you/start dating again.. Try dating (talking) to someone outside of your school. He obviously doesn't care about you why would you bother trying to make him care.. Also, never let your friends get to deep into your personal life.. Unless it's serious (physical mental abuse, drug and so on) good luck
