Should I tell her how I feel?

I’m friends with this really amazing girl, and I recently developed feelings for her. The thing is, she’s going back home (to Italy) for the summer and next year in 3 days and she has a boyfriend there. Shewill come back in 2 years, but its not definite. I don’t want to start anything with her because a) she’s going away and b) her boyfriend has jealosy issues and literary punches whichever guy even talks to her in the face. I feel that I need to tell her how I feel, but I don’t want her to be confused. What hurts even more is that she’s completely oblivious and always comments about how she can’t wait to be with her boyfriend and away from Canada.
