You are right to feel uncomfortable, rather than flattered, by such extreme imitation. Short of cutting her off completely, there are ways to gradually disentangle yourself
I met X about 10 years ago, at the gym. She’s not a very close friend, although I think she would like to be. For the first few years I thought we had so much in common – places we’d been on holidays as kids, our attitudes and our taste in music and clothes.
It has taken me a while to realise that I can’t believe anything she says. She copies everything I say or do. Every time I wear something new, she says: “I’ve been looking for a coat/dress/boots like that. Where did you get it?” She turns up a week later with almost exactly what I have. I simply don’t answer any more.
