My friends been cheated on and I've been supporting her through it but I don't know why it really triggered some horrible feelings of guilt for what I did to my ex. I cheated on and left him really abruptly and the break up was hell for him.
I searched him on Facebook and was scrolling through our old messages, I'm not sure really, just curiosity/nostalgia and I accidentally liked one of his messages. I unliked it but googled and it said he would of got the notification. I messaged and said sorry if you got a notification, I didn't mean to, but I've wanted to apologise for years so I'll take this opportunity to say I'm really sorry for what I did to you. You didn't deserve any of it. I hope you're happy and having a brilliant life.
He screenshot it and sent it to my dh. All I can think is he knew I was married and he thought I was doing what I did to him again and it triggered him or something. Dh upset that I'm messaging ex's but it wasn't bloody like that.
What do I do
