Why is this guy still hinting on fb when he said he is moving on?

The saga continues for this guy. First, he had a lot of things to complain telling me that I am selfish and that I don't really like him. He got upset because I won't call him with a pet name he wanted me to call him in. I told him it was signifying a commitment which in reality I didn't feel yet. Plus, i deactivated my fb when he needed me the most. I did apologize though. He said it seems like he is the only one who likes me and that he wouldn't force things and told me he will move on. After talking to him hours and hours, he still thinks I'm not being serious and I feel he seems to be extremely paranoid about everything I say.

He also has the tendency to want to upsell himself on me. Lately though after fighting me for not being serious. He said he already wanted to level up but will let me go if I don't like cause he is getting tired. True enough, when i sent him a message asking how he is, he no longer responded. I am caught between wanting to explain myself but also not wanting anymore to have anything to do with him. He didn't respond but instead he hinted at his messenger notes saying "wrong move" as if to say it was wrong on my part to do what i did. What should I do?
