I wish you the best of luck. I read your blog and can sympathize/empathize with what you are about to go through. I'm married and my husband followed me to law school and then again when I transferred, so that we didn't have to deal with the distance, but it is still a very hard situation the 1st year. I'm just starting my 2nd year, so we'll see how it goes.
This my view of how it goes the 1st year in a nutshell:
On the side of the law student: The 1st year is really stressful, especially the 1st semester. You feel like you've been thrown in the middle of the lake without any training on how to swim. You either learn how to swim or you sink. So, you spend all of your time, and I mean all, learning how to swim and how to swim very well (and hopefully how to swim better than your classmates). You will love it a lot of the time and hate it at other times, such as when you really, really want to sleep or when it's nearing exam time.
On the side of the significant other: Your significant other is always busy and all they do when they aren't busy is talk about law, law, law. You may find that your significant other's personality takes on notable changes--more stress, less laughter, he/she thinks more critically, has less passionate answers to things--less black and white, starts answering everything with the scrutiny he/she employs when reading cases...
Anyway, I'm sure you've heard all of this before. Hang in there.
