OK here goes. I'm engaged to my partner we are due to get married soon he has two children with his ex wife aged 12 and 9. He has moved 10 miles away from his ex to create a life for himself before i met him 2 years ago. I share the home with my partner and his 2 children whome he has 50% of the time. The children are so happy there seems to be a good routine and good boundaries in terms of drop offs pick ups ect. I talk to the ex wife we get on about the children I am devoted to them my children are adults and live in my other property I'm in regular contact with them and we all have a great relationship. So my partners daughter has a really lovely set of friends at our home. (My partner worked hard to find a nice area so the children felt safe to play out and make friends) my step daughter sees her best friend regular when she's at our home they play together alot her friend mum is a single mum. Anyway my partner and I went on holiday and while we were away my step daughter made arrangements to have a sleepover at her friends house (the friend that lives near us) the ex dropped her off at her friends house and she stayed there for the weekend since the ex has dropped our step daughter off at the friends house on the nights at the weekend she's not with us. I'm absolutely fuming. I feel like this is an issue for me. I appreciate the children being friends but am I right to be angry? I feel like the ex wife is just taking the piss.
