my sister borrowed our family iPad and the kasidie autofill came up. she hasnt said a word in 4 days

i need to type this out somewhere bc my husband is asleep and i cant. so my sister (33, recently divorced, going through it) crashed at our place over the long weekend. we gave her the family iPad to watch netflix in the guest room. except the family iPad apparently had safari open to my profile in the background tab AND the keyboard autofill was set to suggest "kasidie" the second you type "k". she was logged into her gmail on it and went to type something innocent and i can only imagine what popped up. she gave the iPad back monday morning weirdly cheerful. drove back to her place. and since then. nothing. no texts in our sister group chat, didnt comment on the niece bday photo, didnt call mom (i know bc mom called me asking). 4 days of radio silence from a person who texts me 8x a day normally. we are f41 (me) and f43 (husband) married 14 yrs no kids, lifestyle since 2022 mostly online + maybe 4 meets a year. we are not deep in the scene we are dipping toes. what i cant figure out is which scenario is worse. is she silent bc shes processing and shes about to call me crying or angry. is she silent bc she doesnt know how to bring it up. is she silent bc shes ALREADY told my parents or her ex (who still talks to my husband sometimes ffs). every one of those scenarios has me in a different kind of trouble. also weird thing... i checked the iPad history and yeah, she def saw the profile page bc the timestamp matches the night she stayed. she didnt just see the autofill. she opened it. btw the photos on the profile are torsos only, no face. but my husband has a very identifiable forearm tattoo. shes seen it 1000 times. do i call her. do i wait. do i pretend i dont know that she knows
