Some advice please as I am not sure what I should do about this. I have lived with my girlfriend for 3 years, her daughter lives with her granny as she does not get on with her mum. She is 17 years old and has had almost no contact with her dad in the past. Recently her dad has started getting into contact and wanting to see her again - he has paid no CSA in the past and owed £25000 in arrears, my girlfriend told him not to bother paying the arrears and closed the case recently. Her dad never offers any money for anything and I am expected to pay out even though she is not my kid. I have to pay, every month: £110 to her granny for living costs, £50 a month for her mobile, she gets around £30 a week out of me for spending money and she has even asked me to buy her a new passport. She does not work as she goes to college (and makes excuses for not getting a job). Her mum does not work as I work away from home quite a few months of the year and she comes with me - so she cannot keep a job as we are away travelling while I work around 6 months of the year. I worked out that her daughter is costing me around £400 a month, including petrol to take her/pick her up from college which is a 60 mile trip in total each time - going from home to college/to her granny's house/back home etc, up to 4 days a week. And as her mum does not work I also have all the house bills/food, and she smokes so I buy her cigarettes too or else she goes mental if she goes a day without any etc. And I pay the CSA for my own child. Anyone else experienced this and what do you do? Trying to get her dad to help, but he always says he has no money (but always out drinking at the weekends - something I cannot afford to do!)
