Aquarius guy- Whats up with him and how to deal wi

I met this aqurius guy who was totally into me in the start. We went on dates, talked non stop, he could even see himself getting married to me, he sent me poems and was very sweet to me. The after a month of dating he said we have to stop this because he is not able to focus on other things in his life because all he ever thinks is about me, and we should move on. And said he desont have a crush on me anymore.I said ok and kept a distance from him.
After 2 weeks he sent me a text saying he's confused about me and doesnt know why hes telling me this..then the next day he said he was joking. ( i doubt it). If he left the room, he would look back at me...ignore my text sometimes and replies after few hours or a da. Once i ignore him for a week, he texted me saying how are you doing darling. if I talk to him he doesnt look at me, but looks away when he speaks to me..and when i look away for a moment he looks at me( can see form corner of my eye) I dont get him at all. I have all my summer school classes with him and dont know If I should be myself and stay friends with him or just ignore him? Will he come back or he's gone for good? I am a scorpio girl
