should i tell him that i like him

dan

so we are both international students. he had a brief relationship with a girl in our class and everyone knows. i also got involved in a relationship with a classmate but its all over now ( we're still good friend). i always have been having affection for him but its kinda hard to tell since i'm very shy and not really proactive regarding this matter. i have a feeling that he likes me too but both of us couldnt find a proper way to initiate it. also im afraid that if i date him, our study will be affected cos we share the same group in most of the courses (if we fight it would be very awkward). my program will end in April and im kinda waiting for it to end to let him know my feelings for him, but also im afraid that it will be too late cos we wont get to be together again. he will take another course in the same city in May, i will return to my home country during summer and go back to take another course in another city. i really like him and i want to give it a try. however i dont want to hurt the other two classmates and also if he refuses it will be hard for me to work in his group. what do you guys think? what should i do?
