I think it's safe to say that when your partner shares your private business with their parents without your consent, it can indeed be perceived as a betrayal of trust. While it's understandable that family involvement can be a significant aspect of many Nigerian cultures, it's essential to establish clear boundaries and communicate openly with your partner about what you're comfortable sharing and what you'd rather keep private. In an ideal situation, your partner should respect your wishes and maintain confidentiality, especially when you've explicitly shared sensitive information with them. If they're seeking guidance from their parents, it's better to have an open conversation about it beforehand, so you're both on the same page. If this becomes a recurring issue, it may be a sign of deeper communication problems in your relationship, which could be a deal-breaker for some people. Ultimately, it's crucial to weigh your partner's cultural background against your own need for privacy and respect in the relationship.
