I suppose this all depends on the foundation of your guys' relationship and past trust issues.

Whereas I can see the whole "we don't hide anything from each other" outlook, I also am partial to everything doesn't have to be shown to my partner thing.

I've got some trust issues myself and find it weird when my partner won't leave the room I'm in without his phone. That strikes a nerve with me sometimes because it would be in the case that he just forgot his water cup downstairs and I don't understand why he needs his phone to just retrieve his cup. But I think we are all attached to our phones and it's just instinct to not leave it.

But I'm choosing to trust him. It takes a lot I know, especially if we've got some baggage that we haven't unpacked from the previous relationships.
