Trying to Concentrate on School?

I'm falling in love with my boyfriend and we both have extremely busy schedules since we are both in college. I just met him about two weeks ago, but we met and have been inseparable since then, it has been really amazing! But I'm in grad school and trying hard to concentrate on my studies, but it is hard because even when we aren't together, I constantly think about him and have a hard time focusing on my work. Do you guys have any advice about how to find balance when you are falling in love with someone?
