I can definitely sympathize. I know it's kinda hokey, but do a date-night. We do it at a minimum of once a month, any where from dinner/movie to mini golf and pizza. Whatever is fun. We had a missed time in Nov/Dec due to the holidays and a death in the family, but are back on track now. We went out last weekend and my dad babysat. Feb is our 9th anniversary and we are going to see Bon Jovi, Santa got us tickets for Christmas. You have to make the time. Even if its snuggling up on the couch a night or 2 a wk to watch TV, it's better than nothing. During the week we watch the 830 and 9 pm episodes of Family Feud on GSN and play along. Corny, but it works. Sometimes the questions even spark conversation or debates. You've just got to fit in what works. Tomorrow is the weekend, blow off a few hours of studying on Sat or Sun (you won't fail the class) and sleep in and snuggle, lounge in your jammies, go to brunch, the video or bookstore, put the jammies back on and snuggle up and watch a movie or read the new books. Just hang out.
To me the more solid a relationship, the less "doing" there has to be and more "being" While its fun to get all dressed up and go out for a night on the town, it doesn't happen often. You need to be comfortable spending time together just hanging. When we realized that, it made a big difference. It's the old "quality over quantity" thing. If you're studying all day and get up to stretch, eat, use the bathroom, stop by his chair and lay a big wet smooch on him. Before you/he leave in the morning, give him a REAL kiss, and again when you/he come home in the evening. 30 seconds of real time, beats an hour of half-attention time.
But you're not in an unusual predicament, I think we've all been there to one degree or the other. As long as its a short term issue and you're conscience of it and making the effort (both of you) to correct it, it'll be ok. Have you guys talked about this together?
I don't know you personally, so don't take this the wrong way, but I wouldn't go about it in the cliche girly girl whiny we-need-to-talk-we're-growing-apart-you-don't-love-me and burst into tears mess. Just sometime when you guys have a minute "hey, we don't get spend as much time together because we're busy with this that and the other thing and I miss you" will suffice. That's what we generally say. "I miss my husband" or "I miss my wife" and thats the clue to the other that we need to make a schedule adjustment somewhere, or stay up an extra 15 or 30 mins that night just to be together.
Hope some of that helped,
