My 12-year-old daughter and I live in the UK and her dad lives in Spain. Over the last couple of years especially she's said how much she hates England and prefers Spain. I've always been a single mum but I've made a real effort to take her to Spain to see her dad and make sure she spends time with both sides of the family. Over the last couple of months our relationship has become so strained and she says she wants to live with her dad. The thought of not being a presencial parent, there to support her through puberty and the challenges of life breaks my heart, but I worry that she is going to resent me if she stays here. She has more family in Spain and really just me here. I feel like I should let her go for her own mental health because right now she just thinks I'm a terrible parent and she would be happier there. Besides losing her, I worry about her education and once she goes there, there is really no coming back as it would disrupt her studies too much. I feel like I have to let her go so I can still maintain some kind of relationship with her and maybe when she's older she'll come back to me in terms of closeness. I don't think she likes my personality and with me going through perimenopause she probably picks up on my changing moods. Any advice or anyone in a similar situation?
