I'm not going to apologize to my girlfriend for possibly infecting her with mononucleosis
Why don't you want to apologize?
I just don't feel like having a conversation and hearing her complain and cry and all the drama
It's cruel to give someone an illness and be unrepentant about it. She deserves better than that from you.
I may have given the sickness to her but she had it coming. She's a drama queen.
No one "deserves" to be stricken with a disease. If you have issues with your girlfriend, you should directly address them with her. You sound like you harbor a lot of unresolved resentment; you both could benefit from couples counseling.
