Your boyfriend needs to understand that this is an illness and not something you have control over. If he was diagnosed with diabetes you wouldn't tell him "I won't visit you until you are better" or "lets not have that happen again." There is no cure for diabetes, but it is controllable.

It will all depend on whether your boyfriend is willing and able to attempt to understand what your illness is all about.

I wrote a paper on depression which maybe will have some relevance to helping him understand, it is at http://www.idexter.com
