Not sure which category but i have been having an affair with my wife’s sister for 4 years. It was something we had agreed to keep quiet forever. We met again last night discretely. That never came to fruition. She told the man she’s with because she wants to be with him the rest of his life. She is going to tell my wife today. So i am pretty sure this marriage is over. This marriage had a lot of rough patches but we were getting so much better. Yes ill take it as i am the bad guy. It started out of anger towards my wife from willingly having talked behind my back to other men and im pretty sure she physically cheated. It was something very pleasurable and enjoyable for me also and we didn’t stop when we should have. Lives are going to be ruined because of this. I am preparing to file the divorce documents. My wife will never forgive me I am pretty sure about this one. We had a lot of fighting and struggles and issues in past but we had gotten so much better. *sigh*. Nothing stays hidden forever. I deserve the outcome. Our family of 5 will divided and broken.
