hello, just sharing a story of mine and im open to any advice as well.

my narc dad (70) has been cheating on my mum (65) for almost a year now with a vietnamese masseuse. he has been telling my mum (who is on medication for schizophrenia) the interactions (kissing hugging) and texts between him and his mistress. he has stopped giving her money (about $200) every month after seeing his mistress and tips her $50 every time she massages him on top of the massage fee. he sees her 2 or 3 times a week and is thinking of marrying her in december. he does not bring her for her medical appointments anymore since he started seeing this masseuse.

the said masseuse is not able to speak english and they have been using google translate to communicate. they also go out on dates every week and she boosts his ego by saying that she has other friends who are looking for a man like him.

i have spoken to him about how screwed up it is to be discussing how much he likes her to my mum especially when she is vulnerable and fears abandonment. my mum has dedicated her life to being submissive to him and took care of his ex wife, who had schizophrenia too, which caused her a lot of stress and ended up being ill as well. i told him to divorce her so that she does not have to submit to him and live in paranoia anymore as he always shouts and her when he thinks that she is sleeping excessively (her daily meds are drowsy).

my mum is a stay at home wife due to her illness while he is a sole breadwinner. my sister and i are above 21, shes earning about $3.1k while i am actively looking for jobs after the end of my contract since August last year and i keep getting lowballed by employers lol.

is divorce even an option? my dad wants his mistress and her 12 year old son to move in to our 3 bedroom flat when there is already 4 of us occupying the flat.

just stressed about the situation and would appreciate if you guys can share your opinions on this so that my sister and i can give my mum a better life. thank you in advance 🙁
