Crying in front of him several times. It showed me that I actually trust him.
When he self-disclosed something embarrassing about himself to make me feel better.
When he reassured me that he'll be back (back when he went on leave for a really long time)
Getting used to the idea that I have a safe space to go to every week. Also his consistent presence and support.
The fact that he made me feel like I matter and I have a right to feel the things that I feel.
