You have two choices. Tell him, or don't tell him. Find out what either one means to you. If not telling him will be a regretful choice, then, what do you have to lose? But, on the other hand, if you won't really be bothered if you don't tell him-don't tell him..
Seems like you should though. There's no easy way to do it sadly though.
