In September, I was using reddit, had an iPhone, etc. I was generally aware of digital privacy, probably moreso than the average person, but by no means was I knowledgeable.
I was running a beta on my iPhone at the time, for context. I had a short conversation with my roommate while my phone was in my pocket. I took it out to text my partner and pressed the dictation button. My phone proceeded to type out the majority of the conversation I had had maybe five minutes earlier with my roommate. Literally ruined my ignorance is bliss and now I have a Pixel with grapheneos and use almost exclusively open source software with a major focus on privacy. Obviously this is an anecdote from some idiot online and I can’t verify what I’m saying at all, but the experience definitely shook me.
I think that maybe a different way to look at it would be to ask: why is vulnerability a bad thing? Everyone has emotions. Everyone is impacted and affected by things. To use your situation as an example - your partner betrayed you. You SHOULD be vulnerable to that. The fact that they can’t fathom having that level of vulnerability, to the point that they claimed you were trying to manipulate them, is the problem. That kind of emotional invulnerability is what leads people to do the kinds of things they did.
I truly believe that being vulnerable in front of someone, especially when they have hurt you so much, is strength. Showing someone how much they hurt you is really hard. Find people you can be vulnerable with. They’re out there.
