I don’t know what to do :(

So last month ago I was introduced by my friend/co worker to this friend of hers who was single he was super nice, sweet, supportive but also I felt he was catching feelings and I wasn’t feeling those feelings yet it was so soon he caught them I believe and then one night no clue what was going through my mind I told him to leave me he shouldn’t be talking to me since I’m not a good person and he was trying to be supportive and make me calm down he was understanding and told me he was going to give me my space which he did but now lately he’s been acting like a total douche and I’m not liking it he now calls me all late when before he would call me any time of the day, he wouldn’t ask to see my nude body and now he does which is annoying and the past Thursday I told him a situation that happened to me and I was so scared and I cried to him about he and he told me your okay your a strong girl and then asked me when I was going to finger myself and I was surprised he asked me and I said I’m not in the mood for it and he got butt hurt like wtfff man Didn’t you just hear me crying and your telling me to do that for u? Just wow 🙄 also I got a phone call from him last night but I didn’t answer him

What do you think I should do with him?
