My in laws tell me they love me as a daughter and also whenever they call they say goodbye by saying I love you. It's very sweet but I don't feel I can say it back. I am not their daughter, I am their daughter in law, though I very much appreciate the sentiment. But I don't love them as parents though I like them as adults and respect them as my dh's parents and am fond of them in their own right. Is it wrong of me not to say 'I love you' back to them? I know I am very lucky to have this relationship with them - you don;t have to tell me that, but just wondered what you think about the 'love' thing.
