If I feel like I need to check your phone for shady shit, thatโs a red flag. No secure relationship requires that. At the same time you should be able to use the others phone if need be, ex. โhey text back so and so for meโ or โmy phone died can I use yours?โ And it not be weird.
I honestly get super offended when I say โgood morningโ to someone and they donโt say anything back. They ignore me?!?! Donโt ever ask me for shit cause Iโll remember this very moment forever
