My Fiancee's eldest daughter (13 years) is so rude to her father it's untrue. She has no respect for him. My fiancee's father died in April and it was a awful time with my fiancee's mother going through a very difficult grieving process which we still fully not through. When we took the girls away for a holiday in the summer for which the eldest one said it was paid for by her Granddad's money and she had a right to know what we bought with it and how we spent the money because some of it was hers. Firstly we never got any money and secondly it's none of her business. I know her mother encourages her to say things which in turn causes more issues. Every time we have her come over she runs back to her mother and tells her everything we do. Money is a major issue with his eldest daughter who has understanding that things cost money and thinks we are just a cash point. Her mother has since had twins with another man living in the home, for which my fiancee still pays into and all she does in encourage my fiancee's eldest daughter to run back to her and cause trouble. My fiancee and I both work very hard to provide a nice home for the girls and nice holidays and we get treated like dirt for our efforts. The eldest daughter is quite a dirty child and both her father and I keep finding dirty sanitary products all over her bedroom. We are worried we are losing her because she has a bad attitude towards anything we do for either of the girls. HELP!!!!
