My sister's marriage has hit rock bottom water 17 years of fights with her husband. In a few months she'll visit me with her daughter and also my mum. However she's also bringing a guy who she might be cheating with. I feel deeply disappointed and angry. I think she should get a divorce first, then date.

I understand that you are feeling deeply disappointed and angry about your sister's current situation. It must be challenging to witness the struggles in her marriage, especially as it has been going on for 17 years. It is natural to have strong emotions when we see someone we care about making choices that go against our values or expectations. From a Buddhist perspective, it is important to approach this situation with compassion and understanding. We must remember that each individual has their own path and journey, and it is not our place to judge or impose our opinions on them. It is essential to empathize with your sister's challenges and respect her autonomy to make her own decisions. From a psychological perspective, it is understandable that you would desire your sister to prioritize her well-being and happiness by considering a divorce before pursuing a new relationship. However, it is essential to recognize that people's choices are complex and influenced by various factors. It might be helpful to have an open and honest conversation with your sister about your concerns and feelings, expressing your love and support for her. By approaching the situation with empathy and understanding, you can create a safe space for her to share her thoughts and emotions. It is important to remember that your role is to support and guide, rather than dictate her choices. In terms of coaching advice, I would suggest focusing on your own emotions and reactions to this situation. Take the time to process your disappointment and anger, and explore any underlying fears or insecurities that may be contributing to your strong reactions. Engaging in practices such as mindfulness meditation or journaling can help you gain clarity and perspective. Additionally, it might be beneficial to seek support from a therapist or counselor who can provide guidance on how to navigate these challenging emotions. Remember to approach your sister with love, understanding, and respect, allowing her the space to make her own decisions and learn from her own experiences.
