I was married for 10ish years (been divorced for nearly 8 years now). Exh and I had nothing to hide from each other. He would have happily sent messages in front of me and vice versa. We both had pins on our phones but I'm sure I knew his though I never once looked at his phone.
Dp has recently moved in with me though we've been seeing each other a few years and I'm quite taken aback by how secretive he is. If he does message anyone while we are sat say watching tv, he will turn the phone away but even then, he normally goes to the loo or upstairs, messages and then comes back. He never leaves his phone anywhere and he turns it off all the time. This morning he's gone to see his dcs who live with his exw and while I was getting ready for gym, I could see he sat in the car for about 20 mins messaging someone/people.
Other than this, the relationship is ok but I have to admit this behaviour is getting to me - I'm not sure whether it's because I'm not used to someone behaving that way or because he is trying to hide something. Is this normal these days in relationships?
