I started a thread a few months ago about moving in with two women strangers. I'm 36 and have lived alone all my adult life so it's been an adjustment. Overall, it hasn't been bad. They're both more messy than me in communal space but we had a discussion about that when I agree to extend my lease and they have been better. I pretty much took over maintenance (grass cutting, taking the garbage out, thoroughly cleaning the kitchen) because I have higher standards than they do and because I actually enjoy it. My roommates aren't home as much as me so I get lots of alone time not that it matters because they're both decent people and I enjoy their company. Also, my one roommate has a dog that I've grown quite fond of. I've always wanted a dog as an adult but resisted because I work long shifts and I didn't feel it would be fair to the dog. Now I get to walk and play with the dog, buy it treats, etc. But not worry about being its primary caregiver.
All of that said, if I could live alone again for close to the same money I'm paying now, I'd absolutely move. Living alone is awesome, it's just pretty expensive here. My cost of living has been reduced by about 55% since moving.
