I can’t decide whether to get a roommate or not. I’m pretty introverted and not good at meeting new people so I felt that having a roommate would help me come out of my shell. But I’m worried I may not like my roommate and I kinda need that personal space as well- I’m kinda the neat freak type. Any suggestions?
Having a roommate freshman year is a great way to branch out and meet new people – it essentially doubles your friend group (assuming your roommate is in a different major/different clubs/works a different job than you). It’ll also encourage you to go to a bunch of activities your first semester/during orientation because you’ll have someone to go with. If you’re worried you might not like your roommate, find a roommate through Facebook groups for your university. Getting to know someone beforehand and then requesting them as your roommate is a good way to ensure you at least kind of know what you’re getting yourself into.
Here’s an opposing viewpoint: if you can afford a single your first semester, it will be a haven in the onslaught of new people, new places, new classes, etc. That room to retreat can be vital in helping an introvert feel comfortable. You can always have the roommate experience in later years once you get to know some people and have an idea of who else is a neat freak and thus a good match.
Without a roommate, you do have to be much more intentional about meeting people, so leave your door open when you can, especially during the first few weeks when everyone is looking for friends. In my freshman dorm, the girl in a single across the hall brought snacks to our first hall meeting. People tend to like you if you bring food 
A roommate might double your friend group, but that’s a best case scenario. I also knew many roommates who were polite strangers who just didn’t have anything in common (people don’t always tell the truth on those res life questionnaires).
I see both your sides and unfortunately that makes this decision even harder 
If you’re on facebook, meeting a roommate there might be the best of both worlds. You can screen the bad ones out, and try and find someone with whom you click. Does your school offer divided doubles or suites?
I’m going to be rooming with a friend that I’ve known for a couple years now, so it’s not going to be that bad for me to get a double. Getting a double with a random roommate can be a good, bad, or average experience. Most people end up thinking it was an okay experience in terms of freshman year doubles.
