For me, it's the unconditional love/caring that I get from T and no one else. The undivided attention too, all focused on me. No one else cares, or if they do, they are busy with their own life so they do not have 90 minutes a week for me. T shows and tells me that she likes me, and is interested in me more than anyone else except my mother, who is not alive to care about me like that. T provides safety and calmness, something I am working on finding for myself. She accepts me totally, and doesn't judge me. Those qualities don't exist in a RL person, though I have a friend who comes pretty close.

T also provides intensity and excitement for me. That's not so healthy, but part of the deal for me.
