I had a friend I really liked and began to like them thinking they identified as a female because I knew their twin first. For a year I never knew them as anything else from afar. So I always thought She. They told me eventually they used He/They but I couldn’t stop calling them She . We wanted to try a relationship but I kept triggering them and it got to be harmful to us both. I would practice and even try to only use their name or talk very slowly so I could anticipate it . It became so anxiety ridden , we cried together often . I felt like absolute shit I couldn’t figure out why I couldn’t never do it again. We went our separate ways.
