Yeah, thats a tricky one indeed. 1st and foremost you need to know if this guy is going out with anyone you know. If not, then how do you two relate? can you share some of these issues openly? The best way to go thereafter is to try and be close to him as much as possible, spend time with him, tell him how good he is and how lucky the woman he is gonna marry will be. In a nut shell what I am saying is your gestures may send the message across effectively, since I can already see that you are unable to tell him the way you feel directly.\nGood luck and I pray you will soon win his heart.
