My best friend is my cousin. We've grown up together and are just 4 months apart in age. So we are pretty tight.
She is with a fella with this past 7yrs is what i can only describe as having a vulgar personality.the type who acts out in the pub for all to see what he cant wait to do to her when they get home..he is so loud and obnoxious. I'm polite to him for my cousins sake.
Fast forward to the weekend. I was on a girls night with her. It wad obvious those two were texting and as i knew he was out i knew it would only be a matter of time before he joined us.
So before long he was giving me unwanted advise about my marriage...basically about stuff i told my cousin in the strictest confidence. Im talking really really personal things. He made it clear that whatever i tell her she tells him.
So here is my conundrum. Im fuming with her for breaching my trust. Whilst i might tell my husband theyve had a row i dont give details nor does he ask...he knew EVERYTHING about our chats. BUT not so long ago she was planning on leaving him because he is a narcissist who was gaslighting her. Because of this, i think he may have deliberately made it clear he knew all my secrets to cause a row and to isolate her from her 1 good friend.
I've not spoke to her yet about it as im not sure how to handle it.
WWYD about the friends breach of confidence given how manipulative her boyfriend is?
