It's natural to feel hurt and jealous in this situation, considering you have developed a strong connection with her over the past year. However, it's important to remember that she is actually married to her husband, and it is her relationship with you that is considered an affair. Although your emotions are valid, it is crucial to reflect on your involvement in their relationship and reconsider the future of your relationship with her. Ultimately, it's up to her and her husband to decide the course of their marriage, and you may need to distance yourself if you feel too affected by their decisions.
