Confused and hurt.

So i met this guy and we hung out and the first time we ended up having sex and i wanted to but i tried to stopped it like i was like i'm gonna go home but ended up spending the night so we ended up having sex. We cuddled and he was very sweet towards me. So a few days later i snuck him into my house and he spent the night this time and we did have sex and i found out my niece got sick and i started crying and he comforted me and we cuddled all night and it was nice. So then 2 days later he unfriends me on snapchat and i sent him a message on facebook asking him why and he blocked me.. i was so confused. so my sister is talking to his cousin and tells him and he says that the guy i hooked up with said he only wanted to be friends. I felt so bad and hurt and used. Like i don't understand, i never looked for him, he was the one insisting that we hang out and then he did that. it pisses me off and hurts me especially bc the first night we had sex he asked me what i was so afraid of?? like clearly i'm afraid of guys like you. I haven't been able to get him off my mind. This blows 🙁
