Amen, Lyoness. This sounds a lot like my husband. I'm forever grateful that he's not an academic, because he can pull me out of my obsessive thought patterns and remind me that there is life outside of academia. I've been much calmer since we started living together. Which is to say that I'm still a bit of a hyper-competitive stress case, but I don't spend weekends in my pjs eating frozen cookie dough any more.
We met during my undergrad, and then did a year of long distance before he moved to where I was for my MA. Like other people have said, the distance was really good for us. It made us that much more certain that the other person was the one for us, and taught us to appreciate each other more. I will say, though, that long distance is probably easier on people who have low-maitenance relationships. We visited every two months or so, and talked on the phone maybe once every three or four days. It was amazing when we saw each other, but we didn't stress out about day to day stuff. We trusted the other person and had a plan to end the distance. I have friends who have been in LDRs where they talk to each other constantly, to the point where they refuse social invitations because they conflict with a daily phone date. I can see that being a real problem when working on a PhD, since you can get so much out of following through on random social/professional activities, and wouldn't want to be constantly distracted from work.
I applied to four schools--one in our current city, one in our shared hometown where all our family lives, and two in a province on the other side of the country. I luckily got in everywhere, and chose our hometown. To be honest, taking my husband into consideration made me not take the far flung schools as seriously as I may have otherwise done, but I'm very lucky to have a good program in a city where he has friends and support.
My biggest relationship-related annoyance during this whole thing has been people asking in hushed, scared tones "And what will your husband do if you move?!?" As if I was asking something crazy of him to support me in my life's work. "He'll move where we have to." "Really?" It was like he deserved a medal for being willing to move for his wife's career. My PhD is damned important to BOTH of us, people! By the billionth time I got asked, I started fantasizing about saying "Well, y'know, I've only been working towards this every day for six years now, so it hasn't really come up in conversation...." or "My husband doesn't believe that women should be in grad school. We're going to divorce." :roll:
