Problem or not

I’m liked this guy for the past 3 years. And I finally found the courage to tell him, we were dating for about 2 months and then I went to a camp during the summer end and when I came back he texted me that he wants to break up. I didn’t know what to say and asked him for the reason and say didn’t say anything. Schools started now and he was completely ignoring me. And then yesterday he started talking to me like everything was normal, I asked him for the reason then and he just acted like he didn’t hear that and kept speaking. I still like him and I don’t know what do do now.
