Am I overreacting?

Hear me out, me and my bf have been together for a year. He gets sick very easily and I always try to take care of him, especially because it’s usually rough on him. But whenever I’m sick, he’s never there. I’ve been sick with the flu for the past 5 days, I have a high fever and almost never get out of bed.. can’t eat much and usually feel just alone in my sickness. We talked today and I asked him why he doesn’t come to take care of me and he just says that he’s working all day, but I know that if it was important to him, he would’ve showed up. My family takes care of me, but he says that if we lived together then he would have taken care of me. Honestly for me it sounds kinda dumb, like why only when we live together you would care? And I’m scared that if I do move in with him, I’ll be on my own when I’m not in a place to take care of myself.. Am I overreacting on this one? If it matters, I grew up to parents that took care of each other in sickness
