We're not angry with each other or anything... we just don't talk. My mother divorced him when i was six, and it's been a rough ride since. My step father has basically been my father. I have a one year old daughter. She treats my Step dad as her grandfather. My question is, when do i introduce the fact that my step dad is not my "real" dad? I don't want to hide it, but i don't want to confuse her.
