My soon to be fiance and I have not been very close to my parents since they were extraordinarily rude about our relationship from the start, specifically my mom who is a narcissist and control freak. Recently, she decided to tell me that if my partner doesn't ask for their blessing, she will be unforgiving and it will ruin our relationship. We have been together for nearly five years and a proposal is coming this year and very likely this weekend. I told my partner what they said and he doesn't feel like he needs to because it is only important to my mom and not to us. So when the engagement happens, how should I approach the situation and drama with my mom?
