On the basis of the information you've given, it really sounds like he's making it about himself, to be quite honest.
If this is the case, write back and tell him, this isn't about him, it's about you. But be careful not to antogonise him. People who are rather self obscessed can take offense quite easily.
Hope you're not offended or upset by what I've said. It is based upon what you're written above.
