Heart to heart

I was sat in chemistry with this boy I used to be getting with a little bit ago. We were having a heart to heart and he asked me if I ever cried over him, I replied with yes then I carried on with my work then he whispered in my ear "I cried over you too, loads of times" ... Argh!!!! I nearly started crying! What do I do now?! He's getting with another girl and I'm kind of talking to another boy but I think I still have feelings for him...
