I (29m) do not want to be around my gf's (28F) extended family. They are nice people, but get sick very often, and have a habit of touching food with their hands when serving. The last few times I went I got sick, because one of the members had a fever and still showed up. Last time specifically, one of the older family members was recovering from a cold, and my gf didn't tell me, and when I got there he looked visibly sick. She then said "how are you feeling", which clued me in that she already knew he was sick. I couldn't leave immediately, the room was small and crowded, and of course I got sick. The grandparents who come are also very old, in their 90s. I do not want to show up anymore because I cannot afford to be sick for a week every time we hang out, and I think they are eventually going to kill the grandparents. I don't want to be the guy that says I'm never going to family gatherings though as it puts my GF in a weird spot after dating for 7 years. At this point though, I've pretty much decided I'm not doing dinners with the extended family. AITA?
