I am unsure how to go about this situation, I have been separated from my daughters father for 9 years, my daughter is 10. He’s been a minimal aspect of her life with phone calls here and there but nothing consistent. I recently found out he has another child on the way- he has not told my daughter yet about it. I’m not 100% sure of the relationship status of he and the woman pregnant with his child. I do not feel like it is my responsibility to tell my daughter about the new baby but I don’t want to hide it from her either, and her father is not the type of person to see this as important thing to do- is it wrong for me to reach out to the woman and start to try and build a relationship for my child and her soon to be half sibling?
