I don't think DH and I have any privacy lol We know our Facebook passwords, Instagram, emails, phone passwords, everything. And it's not because we *have* to have each others passwords to check up on each other. We've just openly shared them. If I don't have my mobile, I'll jump on his mobile and look at his Facebook or Instagram. We were at the hospital last night with DS & DH took him for a walk outside. I had to wait in the waiting room incase the doctor called us through & he just gave me his mobile to keep myself entertained..
We don't really have anything to hide I guess.. We're very close & open with each other, so it's the norm for us.
