I’m going through this atm, there whole family is narcissistic, I’m about 10 months out of the relationship and I still find it all so hard, what has helped me is reading all about narcissism learning all about it and reading articles about others in the same situation there’s a few Facebook groups you could join to. Don’t engage and grey rock and hopefully they will get bored. Add me as a friend I would love to talk if you want to xx
