Ok help out with this guy please any advice?!?

We talk on the internet bc we live far away. When we met he was sweet and we talked everyday but then things changed...he started acting like a jerk...he called me a wh*re and b*tch....then deleted me and then came back a week later blaming it on me....he said he has changed but that was a lie....he keeps deleting me constantly and then adding me back weeks later.... Should I ask him y? I really like him...he's very moody and keeps asking if I like him and that he is sure that I like him....but when I deny he would get angry...when u admit- he would say he doesnt like me back...

Also, we talked 2 weeks ago and I was being stropy with him then he obviously as always deleted me again and said he wont talk to me....bc he will delete his account...then 1 week later texted me again saying Hi and when I replied with a Hi (my text didnt send bc he had obviously deleted his app again) and he didn't reply.....i really like him and even if he acts like the biggest jerk--his cuteness makes me weak and I cant cut him off unlike him...what does he want from me?!
