What we dwell upon in  mind, we can manifest.  It is time to release your dream, you are awake now!  Death in a dream is not about death of the body in reality.  Dreams are very symbolic.  Take it as a sign to renew the relationship in all love and light.  Then, you will be using its message to advantage!

I disagree with the above, this is a very vivid dream, there is obviously some connection here, something is comming to an end. In my opinion, not your someones life, but more so, your current ability to enjoy life now.

When you dream of someone you love dieing you are expressing the fear of losing them. Naturally we all have a fear of losing our loved ones. But the fact that he is dieing could simply mean that you have noticed a change in him or that some part of him is dead. Maybe he gave up a habit or maybe he isn't spending quality time with you. These are just some of the reasons that you could be having these dreams. But I really wouldn't worry about it because more likely then not, some part of your relationship has changed and you are feeling the loss of it.. Just food for thought.  ;)
