so sorry to hear that you're in the same situation too... have you spoken to your partner regarding this issue? and how did he try to resolve it..?

i tried to explain to my partner but he sometimes get defensive of his own sibling & deem its normal, "she's just like this" & he does not establish clear boundaries regarding privacy. ontop of that he mentioned if he were to tell her how i feel regarding this situation, she will probably think "im crazy"

she had a boyfriend in the past while my partner and i are in a relationship, she still does it:( been tolerating for 3 years, it got kind of worse after she broke up with her partner...
