I (27F) have a narcissistic father in law (68M).
He is great in all other aspects and is very supportive of my marriage to his son. He’s helped us get a home and has even assisted with some of my own personal debt. However, his personality is not perfect (none of ours are). He displays very narcissistic personality traits like : always needing to be right and being emotional if not & it’s hard to get a word in conversation with him and if you do, he will make sure to point out that what you say is not correct. Any time I have opened up, he has made me feel very small or like I need to question my reality. I recently started using the gray rock method but I’m afraid it’s going to make it to where I never get close to him as my FIL. Has anyone had success with using the gray rock method ?

My FIL (M64) has been married to MIL (F67) for about 37 years now. My mother in law is in her early stages of dementia and because of this , a lot of things fly by her. I noticed my father in law stares at women’s bodies for very long periods of time- he specifically stares at younger women. My mother in law does not notice ,or it doesn’t seem like she does. (many times she is struggling with walking , or is wandered off) . I know it’s not my place to get involved in their marriage but I feel like he is disrespecting her and she’s at a disadvantage. Has anyone else dealt with this ?
