Why does my ex keep blocking and unblocking me?

( both 16 ) he first cut me off ( from our friendship ) a couples months back about stupid stuff and blocked me then unblocked me and had marked my messages as spam on Facebook ( basically blocking me ) couldn't get a hold of him, add or message. then he added me on fb I accepted -_- thats when i begged for us to start over like a dummy and he said it was funny how I was the one begging this time instead of him ( because after we broke up in January he begged and begged for us to get back together for a long time. he was trying to make me feel guilty for not wanting him at the time. It's like he was tryin to play the victim. he left me and cut me off from everything in the one supposed to be hurt but he tries to Blame it all on me. anyways I got mad about that so I told him that I'm moving forward. like I was literally trying to get back with him Or at least start over as friends and he was just playin hot and cold and i was gettin confused. then he blocked, unblocked me then marked my messages As spam AGAIN childish. it's been a couple of weeks since that happened and now I just got a friends request from him? Ideas?
