I am really struggling today as I have now been with my new partner for 6 months and my daughter is really not accepting this. My ex and I split 2 years ago. She never wants to stay with him so I have her all the time. Sometimes, she will stay during the week one night. He left me as he had a mid life crisis. My ex and I get on very well and it is all amicable. However, she hasnt forgiven him for breaking up the family. We split years ago but stayed together for the kids but we havent told them the truth. So when we eventually told our kids (she was 12 and my son was 16 at the time), they were shocked as we got on very well. However, I moved on after 5 months of telling them and him moving out and started dating. I made the mistake of introducing her to boyfriend number 1 which lasted 9 months. She also met another brief liaison (by mistake!). Now, I am serious about my new relationship, she likes him, but she isnt happy about me moving on. I put her at the centre of my world but think it is reasonable to see him one night at the weekend. It is tricky as she is never at her Dads but often having a sleepover with friends etc. I am at my wits end trying to do what is best. I want to be with my new partner but I want her to be happy. She is mostly extremely rude and nasty to me. I try not to react and try to just reassure her that it isnt her fault and sorry she has to suffer the brunt of this. What else can i do?!
