By their very nature, intimate relationships make two people tune into each other.
You get a sense of your emotional states. You notice when the other is happy, sad, angry, or perhaps…guilty.
Signs of guilt in a man can take many shapes.
When a man feels guilty for cheating, he may display behaviors along a broad spectrum from gushing with love to hostility.
Initially, your intuition or gut feelings may have alerted you to something feeling off about him.
Now that you sense a change in him, you can pay closer attention using the analytical side of your mind to see if he is showing any signs of cheater's guilt.
