Moving on from trouble!

I was in a stressful relationship (cheated on me after one month) without the friendship factor so decided to break up with him but more like a break. I decided to be friends with him til school starts again in middle August. The guy got a gf the next day!!! A day after giving me crap about wanting to be with someone who wants someone else! Can u believe that?! But my ex still tells me he wants me and loves me and all this stuff while he's dating someone uglier than me! Hell he even tried to commit suicide last night over something he did himself! And people r giving him sympathy like someone bullied him or something 😒 this marked the end for me and him but I don't know how to move on from this and I need help. Yes I found someone but he doesn't live near me like his gf does....idk what to do
