Another silly love question...

So I split up with someone I still care for about 2 months ago. We haven’t really talked at all since then and I was finally starting to get over him, until he unexpectedly contacted me on Thanksgiving. Great. Now I am feeling bummed out about it again. There is a part of me that wants to tell him not to contact me anymore because it’s still too hard, but there is also a part of me that would like to possibly rekindle a relationship with him in the future. I’m torn and confused. I don’t want to tell him to not call me if he feels the same way, but I really don’t know how he feels anymore. What do you think you would do in this situation?
