I'm wondering what to advise my friend because I'm not sure she's right on this one..she was in a relationship with a woman for 7 years and they split up around 18 months ago. My friend helped raise her partner's son from the age of 6 months to age 8 and became like a second mum to him. After they split up my friend continued to have the little boy about 3 or four nights a week, referring to him as her son, even though her ex and herself didn't have much communication. My friend's ex got a new partner and starting posting over Facebook and Instagram things like " love my little family". Every time my friend had the little boy she would ask questions about his mum's boyfriend and then start an argument over it with her ex. Friend has told me lots of times of ways that she wants to get social services involved in the hope that she will get the child back in her life which I don't know is true or not as I've never met her. In the end her ex told her she wanted to cut contact between them and not to see the child anymore as she wanted to move on with her life and settle down with her partner. My friend continues to post pics all over Facebook of the little boy even though his mum has repeatedly asked her not to. She is considering getting in touch with the little boy's biological father ( who walked out on them at birth) and asking him to fight for custody so she herself can have contact. I think this is a terrible idea as the father is now a stranger to the boy. Her ex partner has repeatedly told her to leave them alone and saying it's bordering on harrassment. I don't know what to say to my friend as I think she is wrong on this one, as its not her child, and her mum should call all the shots, although I can see why she is heartbroken after raising a child and then not seeing him anymore. Is friend being unreasonable?
