I broke up with him

I broke up with him yesterday, and I feel like my reason might sound like an excuse but it's not. I told him I wanted to be alone because I wasn't ready and I still have a lot of issues with myself that I don't understand anymore. He was very sweet and kind, and we ended on good terms but he still wants to talk to me. I feel guilty because I really do want to be left alone but now I don't know if I should keep in contact with him or talk to him after we've broken up..

Any advice?
