AITAH for cutting off my mate after he lied about my gf cheating?
I’m 25M from the UK. This happened back at uni but it’s come up again cos one of our mates is getting married.
I was with my ex “Megan” for nearly 2 years. My best mate then was “Callum”. We lived together in second year and I honestly saw him like a brother.
In final year Megan started acting wierd. Going out loads, being secretive with her phone, coming home late etc. One night I saw her outside a bar with this guy from her course. They were stood proper close and he had his arm round her waist. When she saw me she looked shocked.
She told me I was being paranoid and he was just a friend. Callum backed her up and said he’d seen them and nothing happened. I believed him because why would my best mate lie?
Turns out she’d been sleeping with him for weeks. And Callum knew. He said later he “didnt want to get involved” and thought it was better to stay quiet untill exams were done.
But he didn’t just stay quiet, he lied to my face and made me feel like I was going crazy.
I cut him off after that. No big argument, just stopped speaking to him.
Now our uni mate is getting married and Callum is going stag do. I said I’ll go wedding and be civil, but I’m not going away for a full weekend pretending were mates.
The lads are saying it was years ago and I’m letting an old relationship ruin the group.
I don’t think I am. Megan cheated, but Callum betrayed me too.
AITAH for still not wanting anything to do with him?
