Input: So I’ve been dating my boyfriend (Let’s call him Ryan) for 2 years almost. His brother’s girlfriend (let’s call her Michelle) I’ve never been close friends with. I’ve been kind to her in general these past year or so but I don’t know her personally at all and quite frankly never cared to. She’s been dating Ryan’s brother for three years. 

I’m at Ryan’s and his brother and Michelle are over. Ryan takes a call at one point and I’m left alone with Michelle in the living room. Out of nowhere she starts talking about Ryan. She starts saying he’s the most manipulative person she’s ever met and that he’s not a nice person. She goes on about how she thinks Ryan is lazy and how her boyfriend does so much more productive things than Ryan. At this point I’m just dumbfounded at how she thinks she even has a right to talk about my boyfriend like this when she always acts so nice to him? And especially since it’s her boyfriend’s brother.

So I tell him later on what she said because it’s evident he shouldn’t trust her if she hates him this much. He says he never really liked her much anyway (she’s quite narcissistic and genuinely rude to people I’ve noticed).

Later on Ryan tells his brother just inquiring if he knew Michelle disliked him. His brother then confronts Michelle about it and she goes on a psychotic text rant at me threatening me that if I ever open my mouth again there will be an issue. She claims that she “can’t respect me and barely tolerates me” and also that since she’s known them longer than me that I’m “turning her friends against her” She also blocks me on all of social media. 

She’s 25 years old and I’m only 20 (we’re both college graduates as are our boyfriends) it’s ridiculous she’s acting so goddamn immature. As I stated before, I care about my boyfriend and was never there to be her friend at all. 

Was I the asshole for telling my boyfriend not to trust her? Should I have just let it go and not said anything? 

telling my boyfriend his brothers girlfriend was talking majorly negatively about him behind his back
