Okay, I’m seriously struggling with this. I (20F) had this best friend, let’s call her Anna (21F). We were super close, like, grew up together, shared everything, and I thought we were ride or die.

I’ve been dating my boyfriend (22M) for a while now, and I’ll admit, I’ve always trusted him, maybe too much.

A few weeks ago, Anna started acting a little off. She’d cancel plans last minute, always seemed busy, and her vibe just felt weird. But I brushed it off because, you know, life happens.

Then, a couple of nights ago, my boyfriend and I were texting, and he accidentally sent me a message that wasn’t meant for me. It said, “I can’t believe we did that.

I don’t want her to find out.” At first, I thought it was some joke or miscommunication, but my gut twisted in a way that I couldn’t ignore.

I confronted him, and he admitted that he slept with Anna. Yes, my best friend. He said it was a one-time mistake, that it meant nothing, and I shouldn’t overreact. But honestly? I’m still shocked. Anna sent me this weak apology text afterward, but all I felt was betrayal. I couldn’t even look at her without seeing them together in my head.

I blocked both of them. Deleted their numbers, wiped them from my life, just like that. It’s been a week, and I feel so messed up. I’m so angry at myself for not seeing the signs sooner, and even more pissed at them for thinking they could get away with this.

Now, my other friends are telling me that I’m being too harsh. They say I should try to forgive Anna and work things out with her, but I just feel like I can’t. The trust is gone, and I can’t imagine ever looking at her the same way again. Was I too quick to cut her off? Or was I right to protect myself? AITAh?
