I have been in a same sex relationship very happily for 5 years. My kids are 22 and 20, happy and independent. My partner has a 17 year old girl who lives with us 50/50. I moved in with them 1 year ago and it has become dreadful. The daughter and my partner expect me to be invisible on the weeks she is with us. It has been suggested to me by my partner that to keep the peace I not ask her any questions or talk to her and she told me a couple of days ago that when she is with us she will be fully focussed on meeting her daughters needs. The daughter, sadly behaves rudely to me in front of everyone including my own children who think she is from another planet…my son told her that it upsets him when she is disrespectful to me and she laughed at him. She is doing poorly at school because she refuses to complete work, cannot keep a friend for more than a couple of weeks….
Any advice appreciated
