Did I give him the impression that I don't like him?

(Anon please!!)

So basically there is this guy that I have done stuff with once before a couple of months ago and we sometimes talk on snapchat but I usually patch him, take ages to reply etc because he is a player and before I wasn't interested.

But on Friday we were texting a lot and he basically asked me if I liked him (he kept on saying comments like "I know you don't like me in that way" and was hinting at me to say I did) and I told him I did and he was like no way I didn't know etc. Then he was like "oh maybe we could go out one night and I could pick you up" and I was like sure I guess so and he was going to pick me up either on Saturday or Sunday but on Saturday morning I didn't answer his snapchat because it was like the end of the specific convo and I didn't hear from him on Saturday during the day but on Saturday night he went out with his friends and sent me a pic of them but I just patched it because it was kind of like a general snap but then at like 3/4am on Sunday morning he text me when he was drunk asking why I was ignoring him and saying other stuff that didn't make sense and then he was like "so tomorrow night??" But I got the messages on Sunday morning at like 10 and didn't answer because he had been drunk when he sent them.

I thought that he might have text me when he was sober but he didnt and I didn't reply to his drunk messages so we never went out on Sunday. I thought that if he was serious about meeting up he would have text me sober so I assume that he's not interested. Do you agree with me or do you think that I gave him the impression I wasn't interested? He's not text since Sunday morning and has kind of ignored me at school but I can see him looking at me and his friends talking about me. :/ (We are both 17).
