Narcissists display Red Flags. So can your future Mother-In-Law aka potential future Monster-In-Law.
If you have not gotten married yet, then watch for those Red Flags given off by Mother-In-Laws. It’s sound advice given in the video by a female whose marriage was destroyed by her Husband’s Mother.
If the Mother-In-Law shows signs of Narcissism, she may feel that you (being the potential new wife) are competing with her for the affection of her son (her surrogate husband).
