DH takes his phone with him just about everywhere and is always checking for messages when I'm not around. He even takes it straight to the bathroom first thing in the morning (if he hasn't already checked it under the duvet before getting out of bed).
He is on Facebook every night messaging whilst looking at other stuff on the internet. I started to worry about him being so secretive and have been trying to see who he's messaging on FB and it's always the same person. He has exchanged messages with her every day since I started paying attention to it all but it's been going on for months. I can't see what they are typing and he hides it if I get too close.
I asked him who she was and he said just a friend. I told him I wasn't happy with the amount of time he was devoting to her and he got very defensive saying that she was the best friend he had had in years. Since then he is still messaging her except the message box is now minimised to the tiniest size on the furthest side of the screen from where I sit.
I've read on here about emotional affairs but at what point does a friendship cross the line and become an emotional affair. I've no idea what the content of the messages is and no way of checking due to passwords. I briefly see her commenting on his FB posts and these can include a heart or xx at the end but then I sometimes do that with my friends. Any opinions?
