History : my partner has a child with his ex , which is not his biological child but he knew this before birth (as she was already pregnant) . The relationship didn't last long but he stuck by the child.
PRESENT: Any way we've been together 9 years and the she is 10 . They have often questioned me as to whether they are really daddys child , and why they dont look like her brothers . I just said they wouldn't look like them because they are boys and i made them with daddy and im not her mum so that explains the looks . Recently her mother has expressed that she needs to tell the her that he is not the biological dad , after she has seen some papers where he is refered to as 'step father' from when we looked after her for 6 months due to social service intervening . And the mother has recently just had a baby with someone she hasnt even been with a year . Personally i feel its been deribarilaty done , i.e letting her have access to to the papers to be able to ask these questions to try and break contact or something .
How would you think they should go about this ? She wanted to do it in a public places i.e wacky warehouse . And i know im not her mum ,but should i be there aswell ? More friendly faces to show we have been there for her regardless of who made her ?
