I think I know which southern school you are talking about, and if I do, it's where I have chosen to go in the fall. My reason was that it has a great track record of getting their MA students into good PhD programs. I really understand the boyfriend/friends thing...my boyfriend will only be two hours away and I know that will be a rough transition since we went to undergrad together. I can't imagine being a flight away. But I had multiple professors at my undergrad institution talk about how well the school prepares students for PhDs. But, again, like you said, interest plays a large role in the whole process as well. Overall, I know I am probably not helping much but I definitely feel empathy for your situation. Let me know if you decide on the southern school
