As in title, my girlfriend might be infected with mononucleosis (she will test for it tomorrow) and she is currently mad at me at infecting her. I was never diagnosed for mononucleosis, so I am not even sure if I've ever had it and I wasn't sick at all in the last few months. She is convinced that I am responsible for it, even though kissing is not the only way to pass the virus. I really do feel sorry for her being sick, wasting time and money for doctors and missing lectures at uni and family events, but I don't think I should apologize for something beyond my control and for something I may not be responsible for. Reddit, am I the asshole here?
