Wouldn't ever live with another person, my friend. My home is my castle. I'd probably let a cat come live with me, they're cool. But that's about it.

You're in control of your own life. You do need to decide what it is you want though. Once you've decided that, think about how to make it work for you, how to make it healthy. Don't live your life in your brain thinking what if this, what about that. Weigh up the pro's and cons of living alone or with others and decide what works best for you. Then do that.

If, after all of that, you're still not happy, change it back or change it again. That's how wisdom works. It's how getting to know yourself works.
