I am not sure about this one. I see it as he is reaching out to you. I would give him a chance. You don't know where his head is.
When I learned the real truth, back in 1995, it took me 4 months before I called my disfellowshipped brother, who lives right here. I just had gotten so used to not thinking about him at all (16 years) that suddenly it occurred to me that I can talk to my brother now. It all turned out wonderfully well, and immediately we reconnected and never looked back.
Anyway, just my two cents.
