could you send him a letter telling him you don't want to discuss this and that you feel like he pressured you into telling him before you were ready? he'll want to talk about why you feel he pressured you (ie what he did that made you feel pressured) and why you didn't want to discuss this, but maybe that would be easier--and more productive--for you right now. i'd also tell him how you interpreted his comments after you revealed the information. if he's doing something that makes it more difficult for you to want to discuss things with him he definitely needs to know.
