How do I tell him I have PCOS?

Well, you need to tell him, but break it to him gently, and make sure you let him know that you CAN still have children! It's not as easy to get pregnant with PCOS, but it IS possible. My friend has PCOS, and she has a little boy now. My friend's pregnancy went very well, she and her baby were healthy. If he can't stand by you because you have something you can't control, then he's not the man for you. You will conceive when it's time.
