I just have a few questions/comments:
1). You mentioned earlier that you're concerned about maintaining your scholarship at Miami which stipulates that you need to be in the top 1/3. If you're concerned about being in the top third of your class, why are you not concerned by the fact that you'd need to be in the top 10% of your class at most of these schools in order to have reasonably sound job prospects?
2). Your girlfriend seems to be quite accomplished, and if she killed her MCATs then she's probably looking at some pretty amazing school options. Just on a practical note, it'd make more sense to wait and see where she ends up. Basing your law school decision off of where she is right now doesn't make a lot of sense if she's moving in a year. Have you discussed which schools she's interested in? If she's as amazing as she sounds, she really should base her medical school decision off of her goals and ambitions rather than which sub-par law school you're in.
3). You're right in thinking this is a huge decision, because it is. If you're seriously talking marriage with your girlfriend, then I'm going to assume that you're considering starting a family with her as well. Remember that the decisions that you make in regard to your LS choice will affect your children. Personally, I wanted to give my kids the best type of life possible, which is why I followed the collective TLS wisdom of "retake" and am now accepted to several T14 schools. I can understand the rush to just get in and get out, especially when you know lawyers who have steady jobs after attending schools that TLS shuns. But, is that the best you can do? Is settling okay with you? Is accepting the debt fine? If so, then go ahead and walk into that fire, but I'd want to do the very best for my family that I could and these options would not be it.
4). From the schools you mentioned, you're right in thinking that if you graduate from one there is a chance you'll have a job... the problem is that there's a much higher chance that you'll get one that's unsatisfactory in a variety of ways. The people ITT are just trying to give you the best possible advice, which is truly to take some time off, do something with yourself, study for the LSAT, and go to an amazing school that can provide the best life for you and your family.
Whatever you decide, I wish you the best of luck!
