Would you stay with your spouse if he/she was negatively impacting your health?

Let’s say you are allergic to your husband’s semen (rare, but it happens) and so you have to either take medication to have sex, or wear condoms, or sometimes maybe you are willing to suffer with some inflammation just to feel normal for a short time in your sex life.

Or, what if they discovered H.Pylori, the bacteria that causes ulcers, is passed back and forth between people, and you have very symptomatic ulcers, and you constantly try antibtiotics again and again, with temporary relief, but then the ulcers reoccur, because you keep getting reinfected, and seemingly your spouse is a silent carrier, with no symptoms, and even after trying antibiotics for him too, you continue to get sick. (that is totally made up, I don’t think medical science has proven the bacteria for ulcers is passed back and forth, I am not sure how people acquire that bacteria, but just for the discussion let’s say it is true).

Or, if your spouse contracted AIDS or Hep C at work, and now you had to be very careful to not get infected.

Or, if you learn your boyfriends deceased wife died from a very aggressive form or cervical cancer, and the HPV vaccine does not cover the strain of HPV that led to her cancer. Would you risk staying with him? Knowing possibly he is a carrier?

How do you look at these situations?
