Cheaters Of Reddit when did you realise you messed up ?

When she barged into my house, cussing and screaming at me and when she finally calmed down and cried and told me that she would never cheat on me and that I was a fucking idiot for not asking her about it before I went and did what I did!🤦🏻‍♂️😞🤷🏻‍♂️😬 (Before you attack me I was younger and dumber and I was led to believe by someone that I thought I could trust that she did it to me first and rather than ask her about it I got drunk and went and fucked some girl that she didn’t like)!!!
