Advice?

My boyfriend for 6 months just told me he doesn't like me. I asked him what he meant but he said he didn't know and the only reason he told me was because I asked him to be more open with his feelings. I asked if he was playing but he said no. "I love you but i don't think i like you" Now I've been in a lot of relationships but this is my first serious one. I really love him but i feel like he doesn't love me as much as I love him. I don't want to break up with him. Im trying to understand but he's not giving any reasons. What do I do?
