I'm sorry this has happened to you Silent...I know this has gotta suck.

Try not to blame your doctor, if you can help it...he has an obligation to cover all the bases when making a diagnosis. It may've not been the best bedside manner, if you told him exactly as you quoted, but he had to do it.

As for him wanting a break, I'm thinking he's just finding the fear of the prospect of a heart condition overwhelming for him at the moment, and I think this might be his way of recognizing to you that he might not be the best thing for you right now, so to speak. I think he thinks he's sparring you his pain, in a way. I don't think he's necessarily right in his actions, as I do agree that a couple should be able to handle things together, but I think he thinks he's doing what's best for the both of you.

If I were you, if you wanted to clear up the status, set him down and ask him. Based on your post, tell him you want to be there for him through this, as you would expect him to be there for you had the roles been reversed. See where that goes.

I hope I was of a little help. Take care, and God bless.
