how should I do

Hi

My boy friend told me today that he has serious heart attack problems.

And he told me our relationship is one of the most stress thing for him


And he didn't want to terminate the relationship, but he couldn't continue now. He told me that he has to put back his stress body to normal. He said he would feel apologize that if I can't wait.


What does it mean? How should I do? Does it mean we don't have any result?

I should not wait for me? Any friends and experts can give me some advice?

THank you
