Can’t get over him!!

So i’m 16 and this summer i felt

left out cause all my friends have done stuff and i haven’t so i went with this boy who i didn’t have feelings for. We hung a few time but then i met his friend (who was 18) and i like fell in love with him. It was about 3 weeks of hanging out and feeling like i was in a perfect world. He kissed me at stop signs, cuddled, watched movies, and just hung out all the time. One night a snuck out and we had sex(it was my first time). Two days later we stopped snapping and we’ve talked like twice since then. It’s been 3 months since that day and i’m not over him and idk if i ever will be. advice!?!!?
