At the same time, it'd be like if your bf/gf wanted to constantly listen into your private conversations, or wanted to know every private thought you've had. If they want to check your phone to look through your browser history, or look through your text messages, that's not a very good sign of a healthy relationship from their end in the first place.

Someone else likened it to a diary- you have texts with individuals and groups fro different reasons. No matter who it is, you don't want to be constantly sharing your texts with someone else.

So when I approached this question I’m under the assumption this is like an instance based thing. I’d agree that having to report your conversations to your s/o CONSISTENTLY is absolutely a problem. I’m arguing in favor of the concept as a single use thing. Like if something happened that made my gf feel like she needed to go thru my phone for reassurance I’d give it to her, but we’d also be having a conversation about about boundaries and finding out why she felt this way and what can we do together so that it doesn’t happen again
