This is another reason why I believe you should cut all ties with an ex. I understand the circumstances, but you cannot be friends and carry on relationships with everyone forever. There needs to be a cut-off point somewhere. When he dumped you, that was his cut-off point. You are both trying to move on and this cannot happen if you remain in each others lives, even it is just to say condolences. I would just say a little prayer for him, but don't contact him.

There is nothing wrong with sending your condolences.
