I need advice

Some how i still tolerate my toxic narcissistic mother from distance , but my sister who has been always negative i haven't spoke to her in ten years, my mother keeps sending me her pictures and stuff she has achieved, i can fully confirm this is not coming from jealousy perspective but rather it makes me wonder... why my mother refuses to respect my boundaries. It also makes me wonder if she is sharing my pictures and stories with her???
I never asked, but it just irritates me , makes me wonder am i a bad person? She asked me to make amends with her a while back and i said No thanks respectfully,
Because people never change , either you whole handedly accept them or leave it as is, i really hate drama and confrontations and my life has been very peaceful ever since i cut off my toxic siblings, in a way it makes me lose respect for my mother.. should i tell her to stop sharing people i don't talk to lives or stories with me, i am just in fear that she will see it as jealousy or accuse me of being rude 😭😭😭
