PLEASE HELP I REALLY REALLY NEED HELP A LITTLE LONG BUT JUST

[Unrearkep]

This guy liked me pursued me fell head over heels for me then started doing things that made it seem like he didnt like me but claimed he did so I got a bit clingy and then Monday he said he liked me earlier on that day when I asked but when I called that night to talk about it he didnt want to try and fix things with me and just said he didnt want anything to happen between me and him right now.

Saturday night he texted me drunk saying he liked me and all this stuff and a drunk mans words are a sober mans thoughts.

Earlier when I was trying to figure things out with us and he wasnt discussing things with me I texted one of his friends to ask what was wrong with him cuz I couldnt figure him out. Another time I also talked to one of his friends steve who is also friends with me and has offered to give me rides before and has asked me to walk with him to places and steve helped me. Monday when this guy was acting weird before we talked on the phone I texted steve and told him what happened and I wanted to see steves opinion since hes friends with both of us so I asked steve if he thought this guy was being a dick.

Wednesday I had lab with this guy and we didnt say a word to each other in lab and we hadnt talked since Monday night however an hour after lab he texted me

He said: Could you stop texting steve and matt asking them if they think Im a dick? Youre making it worse for yourself

I said: Um the last time I texted steve was mon and I only texted matt onceIm sorry bye

He said: yah exactly thats why Im telling you not to text steve about me he told you he thinks that Im a dick to make it funny and he already thinks that your psycho

He said: Bye.

We had math later that day and he didnt sit next to me like he usually did but he turned back to look at me once during math and a couple times in chem. Today we had math and chem and he didnt look at me in math but he might have in chem Im not sure. Im so confused and dont get him. Why would he be so mean to me all randomly after Monday he said we should just be friends? And it seemed like he was purposely trying to argue with me. Im so confused anyone have any advice on his behavior?
