He teases me a lot, what does it mean?

Hi, so I've been crushing on this new boy at our school, he's like so funny, we talk ever day every chance we get we aren't excactly friends when we talk he always try to make me smile and laugh he is always the one to start the conversation and try to tell me about his day and ask me questions and stuffs, he enjoys talking to me and so do I , I really like him though, i caught him staring at me once and then he smiled and I smiled back it was kind of cute, he always try to talk to me during class and like he doesn't miss a chance to talk to me or joke with me so many things had happened that I can't quite remember cause I'd be so damn nervous, he always jokes with me and tease me but lately he has been mean like not exactly mean but I don't know he's confusing me, when we talk he's usually kind and sweet and such a good person, but all the teasing is becoming too much to the point that he enjoy it, like he likes making fun of me... I told you guys before that he's like funny but he doesn't tease other girls... I'm so damn confused, what do you guys think?
