ethical girlfriend + sickness dilema (brother)

If he gets sick, then they'll both be miserable and keep getting each other sick. If she expects him to be all lovey-dovey with a girl hacking up snot, he should just tell her that he doesn't want to get sick and spread it to other people or give it back to her. Of course he should take care of her, buy her Nyquil and orange juice or whatever...but he should try not to get sick as much as possible. Kinda funny, I'm sick right now.
