Don't try to be cool or hard to get or anything like that, playing games is a waste of time.

Be confident and tell him how you feel, i mean don't be desperate or anything crazy like that, just tell him hey i thought you liked me and then i don't hear from you for 5 months..that's a little strange so what's up?

I've done the whole game playing thing with guys and trust me it aint worth it. Any guy that is worth anything isn't going to play games.
