My daughter is 12. I left her Dad when she was 5 months old. I had suffered years of abuse from him and didn't want her growing up around it. I have never stopped her from seeing him. At first he wanted her every weekend and I would take her the 70 miles there and back and include all her meals. Eventually I saw a solicitor and managed to change it to every other weekend.
He is controlling and sometimes aggressive with her. He hasn't hit her, but attacks solid objects instead. She has started to self harm now and has anxiety. I know the courts would insist that she goes but I actually don't want her to now. He is doing the same to her as he did to me. He is basically a bully. He has never paid any maintenance for her and I haven't pursued that as I have politely asked in the past and he simply doesn't see why he has to! He also has her for a week at Xmas, Easter, and two weeks in the summer holidays. He makes demands at short notice. She misses out on so much as she wants to pursue hobbies etc, go to friends parties but he is inflexible with anything. She is frightened of him and I can't protect her. We dread the time when she has to go. What on earth can we do? There is nothing arranged at the courts as I know it won't make any difference.
