Honestly to me it sounds like he's being the typical highschool douche. The best thing you can do in my opinion is just take time to be yourself work on personal happiness and make close friends that you can trust before you try to make a long term relationship work because if you're not happy alone you won't truly be happy in a relationship.

High school relationships are just learning experiences. I understand what you are going through try being in a relationship for 5 years with your first love and then them having to break up with you for no reason. It sucks and it hurts, break ups are always the hardest but you'll meet someone better. My ex was my first love as well and trying to get over him hurt me a lot but I managed to move on somehow. If you two go to school together maybe try acting like he doesn't exist, I did it and it helped me a lot. Just because because he was your first love doesn't mean he will be your last. You have plenty of time to meet other guys in this world he isn't the only one. He probably just doesn't know what he wants yet, he's still young, my ex was the same he doesn't know what he wants. Try to distract yourself, do something that you love, hang out with your closest friends, etc. It took me about 5 months to move on from my ex but I did with time, it wasn't easy but it was totally worth it. Its just a learning experience, it was for me. I thought i just needed a boyfriend to make me happy but something I learned is that you can't depend on your partner to make you happy. Go out and socialize with other people, go take an adventure or something. Don't be so quick to find another partner, cry it out if you need to, throw away things that he gave you if he ever did give you anything. It will help you heal and so will time. I went through the same thing except my ex broke up with me last year in March, he didn't give me any closure or any reason so I had to make up my closure, and just except that if it was meant to be it would've been.
