I'm so fucking hurt rn

Ok there's this guy I've been talking to. He was so nice and good to me and I really liked him. So I ended up giving him head and after he was so dry and left me on read and was talking to other girls and it hurt me. Like he would take hours to respond to me. I've been feeling like shit about it the past couple days too. He hits me up and me being the dumbass I answer and start talking and all. He starts asking when we're gonna have sex and I say "I wanna do it but not with someone who I feel is using me" and he say "oh what do you mean using you". I started explains how I've been feeling used lately the and he told me that "don't tell me your catching feelings. I thought were just practice buddies" WTF !!!! In like "oh how do you expect me to not catch feelings  If I've done something to you i've never done to anyone ( he was my first)". HE LEFT ME ON READ what do I do I'm so unbelievably hurt rn and disgusted and I feel like shit. Help
