My ex fiance has shown no interest in his 4 month old daughter. He was on holiday with his new girlfriend when she was born and has not been to see her despite living locally. Is it a mad idea to get in touch with his mum via facebook.She lives in France. I am not after money I am just sad for my daughter that she will not know anyone from that side of her family. Would you want to know?...I have a feeling she has no knowledge of her grandaughter.
