Whoa JBizzle that's crazy...I'm a first year and live with a 2nd year PT, PA student, and med student. lol.
I go to school in Chicago, where it's crazy expensive to get a decent place by yourself, so I'm living with 3 others in a nice place that's rather inexpensive (but, I live with 3 other people). It really depends on your lifestyle. I rarely see my roommates, except when we're all home at the same time (which is usually during the day on a weekend or some weeknights), which is nice, but it's also kinda lonely because we all have separate groups of friends, so we're not living with people we hang out with.
Lots of people in my class live with others in the class...some of it has worked out well, others not so much. I wouldn't recommend living with several people from your class unless you know each other beforehand, because if you end up not getting along, it could get awkward.
A few people commute, and they seem to like it. I theoretically could commute, but it would be about an hour and 45 minutes each way, depending on which train I got, etc. But, some people (like myself) are extremely productive on the train, so it might be good. But then again, I'd have to leave my house at like 5:40 every morning, and wouldn't be home until after 7pm some nights.
I haven't decided what I'm doing next year - I know I won't be living with 3 other people again, because even though our apartment is big, our lifestyles are still pretty different from each other (I'm the most reserved/introverted and one of my roommates is extremely extroverted, and the others are in the middle). Ideally I'd love to live with maybe one other person who has a similar schedule to me, but maybe isn't in the program.
If living with your boyfriend is working with you, keep doing it. Several girls in our class live with their boyfriend. Just make sure he's aware of how your schedule will change dramatically so that it won't cause tension between you two.
