I used to just cry and let the tears roll down my face or wipe them with my hands. Once when it was really bad he said "do you ever use kleenex when you cry"...I quickly said no to be sarcastic.

A couple of weeks ago, I was the worst I've ever been, crying hard with my head down and he slowly got up and handed me the kleenex box without saying anything. This was big since he never moves from his chair and doesn't do touchy-feely stuff. Ever since then I've felt so much more comfortable crying in front of him.
