Ask him out (just the two of you), maybe dinner or something like that where you'll have an hour or two of somewhat uninterrupted time. When I was younger I used to do the subtle hints like staying to walk with people I was interested in, then when it seemed like they weren't returning the interest I moved on. I got much less subtle as I got older and it became obvious that wasn't such a good plan. One way or another you should get your answer, if he's interested he'll find a way to make time with you, if he's not he'll find excuses why he's busy for the next month.Do you think there is any way I can find out if he actually likes me or not? Without having to flat out ask him?
