Hi,
You have two options: To sit wait and hope (and then be sorry you did nothing) or be in control..... that means: Be proactive, talk to him (preferably face-2-face) and tell him what you feel and what you wish / want.... dont' worry too much about his answer, you didn't do anything wrong, on the contrary (and if worse comes to worst and he says "no" it's not a disater, simply admit it (so what ????). You have much better chances that he'll say a BIG yes and appreciate you for being honest and brave. Go for it !.
Best regards,
