<human>: Have redditors been in my position? Here is the story.

Both of us are grad students headed towards med school. We have all our classes together and work really well together. She and I think very much alike and have similar goals for life. I didn't expect to find myself falling especially for her when we started school 7 months ago.

Problem(s): She's had a bf for about 4 years now and it has been long distance for a majority of the time. She's loyal and it's this quality that draws me to her. We don't know where both might end up for school next year. We've both said things that suggest no relationships with classmates, although there are mixed signals on both ends (ie. falling asleep in my arms while watching a movie). Classmates already think we're dating.

Things are simple right now with both of us concentrating on school, and I want to keep it that way. My plan is to tell her at the end of the school year and see where that goes. Any advise is greatly appreciated.

Condense the text into a few key points
<bot>: 23M falling for 22F best-friend of 7 months. She has 4yr long-distant bf, loyal yet mentions reasons to break-up occasionally. Lost cause or hope in sight?
