Dd is 6, her father and I separated when she was 18 months and my now dh has been in her life everyday since she was two. They get on fantastically and he is an amazing father. He is selfless and patient and kind and dd loves him and (rightly or wrongly) calls him daddy.
My exH was abusive to the point where dd and I had to leave, have police involvement and live in a hostel. He sees dd one or two weekends per month, often leaving her with his mum. He knows nothing about her, has no involvement in school and won't have contact if she's ill/he has something else on etc.
Dh and I have an 18 month old together, he has two dc who my dd feels are like brothers to her and dhs parents have replaced the lack of my parents in her life tenfold. The thought of dd going to live with her father if I died makes me feel physically sick. How likely would it be to happen? Is there anything I could do to stop it?
