For one thing, watching your partner follow their dreams can make you resentful—or it can make you focus more on your own ambitions. “When I got my acceptance letter, my boyfriend got inspired to make new strides in his career.It doesn’t work out like that for everyone, but both of us are motivating each other to go farther.” It works even better if both halves of a relationship are obsessed with the same thing.Even if you can grade your SO's work objectively, there might be a perception of unfairness among other students.Likewise, if any other situation should arise where one of you might be in a position of authority over the other, you'd need to disclose the conflict of interest and be prepared to resolve it. Concerning written rules you need to find out if any exist in your department, university etc.Otherwise, as Peter Jansson said, relationships between graduate students are very common and aren't likely to cause academic concern. you will certainly not be the first or the only couple in this "situation".Around this time of year (read: Valentine’s Day), it’s hard not to notice—try as you might—that everything’s suddenly turning heart-shaped.
I am currently dating a Ph D student in the same department as me (I am also a Ph D student).
One possible thing to watch out for: in some departments, graduate students may work as teaching assistants for graduate courses.
You should ask not to be assigned to TA courses which your significant other is taking (and he or she should do likewise), as this would represent a possible conflict of interest.
My boyfriend’s MFA is in writing, obviously something that I’m interested in as well, and he sometimes jokes that by being with him I’m getting a free MFA.
I get to go with him when poets and novelists come to his school to read their work, I get to read the literature on his syllabus when he’s working on something else, and I get to have great conversations with him about writing.
