by no means am i an expert, but maybe, just maybe, he is having feelings of insecurity - maybe he is feeling finally for REAL what it felt like for the shoe to be on the other foot
maybe he has extreme empathy for you right now, who knows where it came from, but maybe it all of a sudden hit him and he realizes what he just about let go, and he really can't handle those feelings
i don't know, it just sounds terribly insecure - mixed with guilt
