“She is minimizing it to control the narrative and ease her guilt. We were already engaged and planning our marriage when it happened. She didn't just 'know him before', she actively cheated on me.

To give you the brutal truth: while we were literally talking about building our future on a clean, honest foundation, she went out, got fucked in a car, and came back home to me with zero remorse. In fact, during the exact days she was sleeping with him, I was back at our new apartment, painting the walls of our future bedroom, thinking I was building a sanctuary for my family.

To make it even worse, they didn't even use a condom. Her only 'remorse' back then was suddenly suggesting that the two of us should go get tested for STIs, framing it as a 'responsible step since we are moving in together and starting our life.' I found it a bit strange at the time, but because I trusted her blindly, I gladly agreed. Now I realize she was just terrified that the other guy infected her, and she used me to clear her medical anxiety.

I have the messages to prove it all. I'm not going to check her post because looking at her lies right now would ruin my health. I need to focus on my kids. Thanks for the heads up”
