Hi there,
Sorry to hear about your pain. Believe me when I say I know what you are going through.
I have given some recent advice to someone else and rather than repeat it, I will just provide you a link to it so you can read through. I think a lot of it applies to you and how you can get through this very difficult time. You might need to reverse some of it as this guy is talking about his ex girl, not guy, but it does not matter because the circumstances are not altogether very different and the solution is mostly the same.

Will you get him back? I cannot really answer this but it shows that he cares by him contacting you.
Don't let this however build up any false hope and believe that this could in any way be an indication of the two of you getting back together in the near future.
Sometimes when the dumper contacts the dumpee, I think it is because they are feeling so much guilt and they need to know that the dumpee is o.k. The best thing you can do is keep yourself busy and try an move on without him, at least for now.
I wish you well..
