I rejected him and he deleted me?

Hi, I've been speaking to this guy for 3 months and have seen him a few times. We told each other that we both weren't looking for anything serious but agreed to still speak and have 'fun' together. We would have deep chats and he would stay over sometimes. Recently I messaged him nicely telling him that I didn't think we should see each other again. He ignored it and then deleted me off everything. I don't understand why?
