My Mother-in-Law's Secret Conversations Behind My Back! 😱💔

Hey everyone, I'm feeling so confused right now and really need some advice! 😔 For the past two months, my mother-in-law and I have been getting really close. She calls me every day, helps me decorate my new apartment, and we spend every weekend together doing family activities. She even talks about future holidays and family plans with me! 💕 But yesterday, I accidentally discovered she's been having long phone conversations with my husband's ex-girlfriend's mom, sharing personal details about our marriage and my struggles with fertility. She's also been texting other family members about things I told her in confidence! 😭 We never established boundaries about what stays between us, but I thought we had that understanding. I really care about building this relationship, but I'm so hurt and don't know if I should confront her or just let it go. Have any of you dealt with something similar? I feel like I'm losing my mind here! 💭 #MotherInLaw #FamilyDrama #RelationshipAdvice #FamilyRelationships
