I have a 16 year old daughter. Her father left yes when she was three years old for another woman. Since then he has seen her regularly. Up until a year ago, it used to be 50/50 care. Then he decided to leave his partner and their child together and move 3 hours away for ‘work’. It turns out he had been having an affair and he was moving to live closer to her. He kept up the pretence about still being with his partner until this summer (he met his new girlfriend late last year) and took our daughter on holiday with her. Then in the space of a few weeks, he told our daughter that the relationship was over, he was in a new relationship and he introduced our daughter to her and her family. This was understandably a shock, as her step-mother had been in her life for almost 13 years. He has also now dropped down to having her every other weekend. My daughter was quite upset about him moving and abandoning another family - after originally doing this to her.
Recently she went to his for the weekend and came home quite hostile and argumentative. I had very stern words with her after she began shouting and throwing things and she stopped speaking to me. She ignored me for a full week - only coming out of her room for meals - before I advised her that if she didn’t apologise, she would need to spend the weekend with her dad - as I found her behaviour rude and disrespectful. She chose to see her dad and then refused to come home, saying that she now wanted to live with him. I have struggled to understand this. We have never had any problems in our relationship until that weekend, and all I had done was tell her off for her rude behaviour. She has returned home now, as she is in her last year at school, but is making it clear that she doesn’t want to be here and is continuing to ignore me and sit in her room all of this time. She is saying once her GCSEs are finished she wants to move to her dad’s and he is constantly telling her that he will do anything to make her happy and wants her with him. This is so hurtful to me, when I have done everything for her for the last 16 years and he has just continued to behave selfishly and put himself first. What is going on?
