I just got back from a weekend with my narcissistic in-laws. My narcissistic father in-law married his narcissistic girlfriend. Once again, I am still realizing the shots they threw in their sick covert manner. I so wish I had recorded the toasts. All of her families’ toasts, including her own, were about what she/they had gained from him, and what he has done for them. My husband’s families’ toasts were about how she made him happy and put a smile on his face again. 
The following link is to a blog post about the last time I saw them 3 years ago. I cut them out of my life after that, but agreed to go to the wedding if my husband talked to them first about how things are going to go from now on, meaning no more passive aggressive bullshit.
