Living with a roommate is extremely easy as long as you keep similar(ish) hours, communicate well and consistently, discuss (not dictate) mutual rules, and occasionally feed them.
It is like having a pet, except waaaaay easier.
**NOTE***
It helps if both participants are reasonably sane, and of the human persuasion (mer-people, aliens, and robots look good on paper but BEWARE).
It also helps if both people are willing to forgive small mistake/foibles in the other, and gives the other person space.
Your roommate-ship will be fantastic if both people are good at engineering excuses to sleep elsewhere on occasion. Or have a partner(s) who don't mind volunteering their place.
For introvert the pros if any don't out weight the cons.
This is true when you have reasonable roommates and not super extroverted, bossy and controlling roommates .
If you really feel this way then I'd seriously start getting new friends if I were you.
Me and my roomate respected each other's privacy.
I routinely wish to rip the vocal chords out of her throat and strangle her with them.
However I refrain. Not that she pays her bills anyway.
Make sure whomever you're living with has the same taste in music as you, you're both on the same page about loud sex, they are financially stable and they can respect the cleanliness of your shared spaces.

I did the roommate thing. I will never do it again if I can help it. The good times only last for so long. And if your friends it tends too kill the friendship in the end. When I was younger and liked too party and drink on the weekends it was nice to have a drinking buddies. I don't drink much anymore and I am not friends with any of my old roommates either. Go figure lol
