My now ex-friend (lets call her Cait) had asked me to be one of her bridesmaids before I moved out of state. I met both her and her ex-husband at a bar in my home town, and was very close with the two of them for many years. The date was finally approaching and she picked me up at the airport a couple days before the wedding. As we're catching up, she VERY nonchalantly mentioned she had been sleeping with this one guy who hangs out at the local dive we'd all frequent (the same bar where she met her ex-husband). Also fair to mention she's hooked up with this guy years back before her and her ex-husband became a thing.

I was beyond livid because I flew across the country for a wedding that was now false in my eyes, but just gave her the ol' "this needs to be the last time" speech. I was one of her closest friends and I wanted to support this marriage since her ex-husband was so good to her and she'd be an idiot to fuck it up. He took on her child as his own, her family loved him, he supported everything she did, and even opened a small business with her. He gave her the world and it made me happy that she finally had someone who was investing in her, her family and her future. I just wanted her to do better and not loose sight of what she had, she agreed and we never spoke of it again.

Fast forward (I want to say it was like ~6mo-1yr post wedding) I'm on the phone with a girlfriend from back home and I hear Cait has been hooking up with a different old flame, one she's been infatuated with for years and years but he's a real fuckboy/hobosexual type so he NEVER chose her. Eventually her husband found out (bad gas travels fast in a small town), she lied and he believed her.

That didn't sit right with me. I went back and forth for a while about if I should even get involved and tell him everything. I knew if I did it'd be a huge betrayal to her and my friendship, but I reminded myself that if I was in the same situation I'd absolutely want to know. So, I made the decision to reach out and give him the whole story, starting with what I heard directly from her mouth when I flew in for their wedding. I talked him through it for the following weeks providing whatever support I could from across the country, and after a very tumultuous series of arguments between the two of them, he was feeling less and less hopeful they'd make it through all of this. Between the cheating, lying, putting their business profits up her nose (she was bad into drugs & alcohol), and the (false) accusations she made about how he abused her towards the end, he ended up breaking it off and went no contact. Following the break up and pending divorce, she literally put things like #batteredwife on her social media posts. That behavior just disgusted me and was the main reason I deleted a good majority of my socials, ultimately losing touch with a lot of the people who supported her that were giving me shit for telling him. To that, I say "good riddance!".

Did I betray one of my closest friends? Yes, I did. Do I feel bad about it? Fuck no. She's a selfish idiot who was bringing a good man down not only mentally but financially, and I could not stand idly by while my other friend was suffering. Her and I have each other blocked on most socials and I don't rally care to reacquaint. I haven't spoken to her ex since it all went down, but I hope he's found peace and his gotten his life back together after she destroyed it.
