I Can Look At My Boyfriend's Phone, But I Don't Have To

My boyfriend and I have a great phone policy that I wish everybody were lucky enough to have. I'm allowed to look through his phone, and he's allowed to look through my phone. But we never have, because I don't feel like I need to, and because I don't want him to feel like I'm invading his personal space. I wish more people could establish healthy boundaries and attitudes concerning technology and social media in relationships.
