hey,
i know it must be really hard but im sure its nothing personal towards you, maybe she is just going through some changes or difficulties in her life and wants some stability and 'comfort' right now which is maybe why she wants to stay at home. Sometimes you just need your mummy! a psychologist sounds like a great idea to help your daughter work through her issues, there may be things she needs to talk about that she doesn't feel comfortable sharing with either you or her mum. In the meantime, just let her know you are there for her and love her and in time im sure she will go back to her old self! good luck

I totally agree. Children go through all kind of stages at every age. I'm sure it's nothing personal either. My daughter goes through days where she wants only me and some days she wants her dad. You can't take it to heart. And I also agree that a psychologist is the right answer. I wish you the best of luck in getting things sorted out! Take care!
