she is sick, people who are sick feel like crap, don't expect them to be loving, caring and friendly, she wasn't any of these things just before she got sick but you expect her to lighten up and be caring, cheery and happy while she's coughing up a lung?! Seriously? Give her some space, she is sick and she wants to rest and get over her sickness, she doesn't want to think about your relationship and improving it or becoming a better partner for you, just do your thing and let her be.
