If we stay together then we will likely catch the disease

This is a little different. My husband and I are older. We just celebrated our fourth wedding anniversary. We started dating after I had been widowed for a couple of years. My late husband died unexpectedly. We are both Emergency Dept. Nurses. He is 65 years old with comorbidities. I have been begging him to stop working because w/ COVID his risk of dying is 15-20%. If we both continue working we will only see each other through "surgical" masks, goggles, gloves and plastic gowns, as we work opposite shifts. I don't want to lose him , so I am begging him to quit.--- Then I will be on lockdown at the hospital without him. If we stay together then we will likely catch the disease, because we don't have the appropriate Personal Protective Equipment (PPEs) --- No N95 masks, No Tyvek suits, No Negative pressure rooms. No instruction on doffing and donning except youtube. He says that if I get sick, if he quits, then he couldn't live with himself. He says he is not so much afraid of dying, but he is afraid of leaving me alone. We both have seen a lot of death and illness throughout the course of our careers, but we both have acknowledged to each other that what is coming is possibly beyond what we both can endure. Still, he refuses to quit while I work and I will continue to go to work. I wish we could both quarantine.
