You certainly have a tough choice. This reminds me of one of those LSAT writing samples. YOu have two choices and some basic criteria that you must evaluate.
Go with Whittier. Like you said, the school is slightly better for many reasons than Fl. Coasta. Costa Mesa is a wonderful area. Your family will miss you, but even in Florida, you won't get to visit on the weekends during law school. You'll only be a flight away. Your BF is in Cali. He wants to stay in Cali. That's a good start right there.
If, and only if, coming back to practice in Ga. is your #1 consideration, then I'd say go to Florida. You will be closer to Georgia, and that will make it easier to network your way back into Georgia. You may even be able to find summer internships, etc...but you will have to do your own leg work. Getting that work done from FL is easier than doing it from Cali.
Keep us posted.
Oh, you could always do Eenie-meenie-miney-mo...
