What else can i do? (guys opinions would be appreciated!)?

im pretty sure he knows.. but doesnt act on it... friends turning to relationship.. dont recommend.. you should have told him from the get go.. but considering that you wont tell him up front.. your body language is all you can do.. try a kiss.. thats all you can do short of telling him you like him... if then it make it weird for him... you know where he stands..
