Yes it’s been 10 years so we often sit in silence, especially if watching tv or on our phones (this happens too much). We have deep chats where no topic is off limits and playful chats at other times, sometimes we have a right good gossip too.
We spend a lot of time together as we both work from home, no kids, and spend all of our annual leave together, so there’s bound to be silences. When DH has been away from work and calls me, we suddenly have loads to catch up on, so I can see how distance/time apart makes for better conversations when reuniting!
