It felt comfortable, like doogie said. I didn't worry about her letting me down - not because I thought she was superhuman or infallible, but because I felt like it would be ok even if we had a miscommunication or she did something that bothered me. I had confidence in the strength of our relationship. I felt secure in her caring and her intentions towards me, and didn't need to depend on analyzing her every action to validate our relationship. I regarded her as just another human being, and didn't expect perfection.
