It's okay to talk about it, it's okay not to. If it were me, I probably wouldn't decide until I actually got into session. Sometimes seeing my T in person (especially after a long break) solidifies my feelings--I find, actually looking at him, that the thing I thought didn't bother me actually does, or the thing I thought I was angry about suddenly doesn't seem important.

I hope you find a solution that works for you. Good luck!
