Why do so many people suddenly think it's acceptable to continue to live with their parents into adulthood?

My viewpoint is I’d have to have a roommate if I moved out on my own anyways. Rent in my state is rather high and my income would barely cover a months rent and utilities on top of my already standing bills. There’s just no way I could afford to live alone, and why would I roll the dice hoping for a decent roommate when I already know my mother’s habits (as well as my brother’s) and I know I can rely on them. Why would I put myself in the position of someone not paying their portion leaving me stuck to foot their bill, too? Or eating my food? Or using my stuff?

After I graduated high school, my mother moved out of the apartment she rented leaving me to pay the rent and moved almost 2 hours away from our hometown. I didn’t see her except for Christmas for several years after that. I had 2 friends move in to help cover costs, so it wasn’t too much of a burden on me. Unfortunately, one roommate was always late with her share.

Why is it not acceptable?

I honestly don’t care what people have to say about me living with my mom and brother. These 2 people have always been there for me, and unless you’re willing to pay my bills, there’s nothing more to be said.

Fast forward to me, my husband (now ex) and son moving to Florida in 2001, where I asked my mom to move with us. It took her a few months to wrap up her life in California, but she arrived 3 months after we did, bringing my adult brother with her. We all lived together in a big house and things were great.

The end of 2011, beginning of 2012 I became divorced and was losing everything, including my home. My mom and brother moved out not wanting to be in the middle of my messy divorce. It’s a very long story as to why I didn’t get anything from the divorce except my personal belongings like clothes and make-up, but we won’t get into that right now. Just know that the divorce literally took everything I had, including my job. I was left with only heartache. The only place to go was to my mother’s where she and my brother had rented an apartment, and though it only has 2 bedrooms, we made it work, and we still continue to make it work.
