Advice needed!!

Okay so this is me and my friend (FWB?), Saul. Recently me and him both admitted to each other that we have feelings for each other, and we ended up sleeping together. Problem is that at the time we were both in relationships, and he's one of my friends exes. Now my whole school has found out that we slept together, 4 of the people i used to call my best friends won't talk to me, and both me and him are getting tons of people crapping on us for it. I like him a lot and I lost my virginity to him, but I don't know what to do... Should I move on with him, or without him?
