can she trust you after what youve done ????
you are both entitled to password your gadgets, and some will say you are both daft not to.
ask her if her trust in you has change cos you can no longer have access to her phone. she may offer you the password. Or she may say you're crowding her.
you could password your own phone and see how long it takes for her to comment.
Maybe you just need to realise you aren't the papacita you thought you were.
