I don't know what to say other than - you would've hurt him either way. People don't always "want" to hurt the other person.. it's inevitable. Bad coincidence with whatever happened with his family but it has nothing to do with you other than it being an extra blow. That just isn't your fault that he's had double the pain in "practically the same day". It's not like you purposely dumped him the day he had to go to a funeral or something tragic. You can't feel guilty for that.

I don't understand the "natural scent" thing but then I don't like guys with beards. Could it have just been bad breath or aftershave you were smelling? Or whatever he washes his face with?
