Hello both me and my partner both have a daughters of the same age from previous relationships, my daughter lives with me and my partner had recently started living with us and his daughter stays at our house every other weekend. My concern is that when his daughter visits we do nice things as a family with the kids but on a day to day when his daughter is not here I feel as though he makes no effort to engage with her after work, he just sits there on his phone which I feel isn't fair on my daughter as this is her full time home and I worry she may start feeling like she only matters when it involves his daughter and I don't want her to feel like this especially if she is expected to share her room with his child and her home with him am I right to feel this way
