Cheaters are often in their own fantasy worlds.
They might think they get to dictate the narrative and reality; however, they find that they do not truly have that power. This frustrates and angers them. So, watch out when you set that boundary.
Some might want to revisit your relationship and talk about “what went wrong.” This is a Trojan Horse.
They do not lack insight into what went wrong. What they lack is your agreement with their narrative about how YOU were at fault for what went wrong.
To sign up for that revisiting conversation is merely to sign up for an emotional beat down by the cheater. Please don’t!
The cheater might feel the need to soothe their conscience after the fact. They might want to enlist you into a narrative where you are now “friends” without them ever taking full responsibility for their abusive sins. Engaging in such a conversation is neither good for you or them as it sets them back from godly repentance.
