My friend “Zali” likes a boy in my homeroom, “Xavier”. It wasn‘t until recently that I started liking Xavier and talking to him more often. Zali noticed this and we got into a huge argument. She thinks I shouldn’t try anything with him because ‘she liked him first’ and ‘I was trying to steal her ”boyfriend”’ because I was JEALOUS of her. I yelled at her back and said that she simply couldn’t stand the fact that he could like me. What’s more, she’s dating “Noah”, one of my friends. She’s made me swear not to tell him ages ago, but now I feel just plain rude and I want to tell Noah so he can be with someone better than Zali. AITA and should I tell Noah?
