Information I don't share... Well mostly private stuff about how we interact in private, how much we have sex and what we do, how bonding and connecting that is. Any details that my partner has asked me to keep private or I have understood to be private. That kind of thing.
All my relationships are love related though, so that might make a diffrence. I don't think I spared details when I have had relationships not based on love. Why bother hiding it I thought, it was meaningless in terms of depth and connection.
I am wondering if perhaps he fell in love, or maybe went out and did stuff that was kinkier than perhaps he thought you were willing to know about. Please do message if the details might help in this and are not for public consumption. I am willing to hear and see if it does change my perspective
