Confusing exboyfriend?

So i went out with this guy for a year and we broke up but we kept talking on and off for another 8months but he said he doesn't wanna lose me but still didn't know what he wanted so i completely blocked him from everything, social media etc. Then the other night i was at a gig and as i was leaving someone grabbed my arm from the crowd and it was him, he's gone onto someone elses facebook to contact me. I dont know what else to say but what does he want from me sorry im very confused
