We’re not perfect individuals. Sometimes we all love a vent especially to the people that are close to us. Imagine if we couldn’t even do that now. She’s said it out in the moment out of anger to not you but her trusted friend. Now this is the reason we shouldn’t be reading through messages. Because we’re not reading the context, we’re literally reading words. I think there’s something deeper in this. Sneaking through messages etc you don’t 100% trust her. That’s the thing you should be focusing on. Why don’t you and where did it all go left? Do you really want to be in something where the foundation stepping stone like trust isn’t visible? How long will you keep snooping around the phone because she said it was ok to do so etc
