I am fuming. My DD9 has just come back from her overnight stay with her Dad and his girlfriend has decided to give my daughter a chat about sex and the facts of life! Bit of background, I have a DS12 and DD9 and I split from my XH 6 years ago. He has been with this girlfriend for 2 years, she has a DS9 and they are about to move in together. I am engaged and 5 months pregnant, my fiancee has 2 ds's.
I feel that she has taked away from me a special mother/daughter 'talk' and I wanted to be able to expain things to her not someone else. Also I haven't had this chat with her yet as I don't feel that she is ready at the moment and she hasn't been asking any questions (she is a huge chatterbox so if she was curious she would ask). My XH was in the room when this was going on but didn't say anything.
As a step parent to be myself I would never do this and I feel angry that she has crossed what is in my mind an unwritten boundary!
