We have been a mixed family for 3 yrs now, I have two children of my own who live with me and my partner and he has two girls who we have evry wknd and Thursdays after school for tea and one of his girls on a Friday as she goes to judo which my partner is the sensei. We all get on really well, theres a lot of love in our house so I was a bit surprised to find out his oldest (11) has been txting her mum saying that she`s being getting told off (when she isn't) and that she doesn't want to be here. My partner and I are very fair with all the kids, he tells my two off if they need it and vice versa there isn't any favouritism. Should I tell my partner what ive found out or should I leave well alone?
