My boyfriend is in a coma. We lived together prior to this and I actually took him to the hospital right before he fell into the coma. I am a nurse.

This is the clasic battle of people in a profession , even for good intentions, being involved in controversy when dealing with other in the same profession. It may rise to defemation depending on what is said and why, BUT, you will have to decide do you spend thousands and possibly tens of thousands of dollars on such an case? If not, then its not an issue to push on and you focus on others.....
