I moved out two years ago, but really moved out "emotionally" four years before that when I left for university.
Despite the geographical separation, there are still a lot of connections. I pay for YouTubeTV which they use. They pay for Netflix & Prime & Hulu which I use. I'm on their cell plan, but I pay my costs each month. My point is that where it makes sense, there is nothing wrong with shared expenses. But I do think it's important to carry your own weight.
I'm happy to answer any questions you have. 🙂
