Trying to keep this as vague as possible. My mentally unstable, narcissistic ex is sending things to DD for Christmas in the post. We've been NC for years after multiple drink/drug/aggression incidents. He only met her once when she was a baby. Has always been NC as he is unable to keep up any level of consistent contact and goes AWOL frequently. She does not know him, yet he's sending things from 'your daddy' which I luckily managed to hide before she read. I don't know what to do. Send it all back? Ignore?
