Help meplease

OK so me and this boy have been snap chatting for like a month OK we didn’t like each other we didn’t talk to each other it was just like benefits basically and I was fine with that because at least I knew that he didn’t have to talk to me I didn’t get hurt when I heard he was flirting with another girl because I knew were just nothing we’re just benefits like all we do is text at night like every night basically we send stuff. So all all of a sudden he goes are we talking with a question mark?And I go are we? And I didn’t know what to think because I didn’t think he liked me I thought we were just sending buddies . And he goes it’s up to you so I was like sure and he goes so you’re my girl and I said yeah, and he was like were going to make out at school and like yeah. So it’s Monday and he doesn’t say one word to me he hasn’t text me all day I saw him in the hall he saw me he didn’t even come talk to me like I thought we’re talking. And I honestly don’t know what to think like are you just using me but he’s the one that asked if we’re talking I didn’t bring it up he did he started that conversation so like if you didn’t want to talk why would you just ask it. Idk what to do should I leave him should I say were done should I just keep sending every night. I’m sorry that I typed so much but I’ve been crying all afternoon and I don’t know what to do I just need someone’s help please just comment what you think you can be mean you can be nice I don’t even care please help me because I can’t take it anymore
