Reading these few pages makes me feel some of us are living in an alternate world. For married guys here whose phones get checked by their wives and have to find ways and means not to be caught, it's probably too late.
But for those who are single, dating, newly married, or saying the vows soon, you still have a chance to set a healthy relationship on an equal footing. You want to set boundaries and give each other space. Not just cheonging but marital life in general.
Speaking as a long married guy, trust me, not all women are insecure about their men (because this is what it boils down to). I wish the second group of guys good fortune and great adventures
