my ex

My ex boyfriend were together for a year and almost a half but then he decided to break up with me because he no longer had feelings. I'm 16 and we've been broken up for about 6 months now but I still miss and (what I think love is) love him. I recently had to switch classes because I couldn't even stand being in the same room with him n it hurt to see him doing ok without me while my heart is hurting. Any tips or way to help me get over him. I've tried going out with other guys but I'm still hung up. He was also my first. So I've even tried sleeping with another guy who I thought could be something more but I'd didn't work out. Advice please. ❤
