Title: Woman Feels Betrayed After Sister Dates Ex-Fiance

A woman expresses her feelings of betrayal after discovering her sister is dating her ex-fiance. The woman, who has been separated from her ex, Anthony, for eight years, shared her story in a recent letter. She ended her engagement to Anthony, who she claims was insecure and belittled her throughout their 30-year relationship. Despite their split, Anthony remains connected to her family through their daughter and grandsons, which she finds troubling.

Recently, the woman traveled across the country to surprise her family during her niece's 40th birthday party. However, the surprise took an unexpected turn. During the meal, one of her sisters revealed, "I’m gonna tell you something, and I don’t want to hear anything about it. Anthony and I are in a relationship." This announcement not only disrupted the celebration but also left the woman feeling deeply betrayed.

She has since reached out to her sister via text and email to express her feelings, but has not received a response. The woman is now uncertain about her relationship with her sister, feeling that dating her ex violates a "sister code." She suspects her sister may be motivated by Anthony's financial status, which adds to her feelings of betrayal.

In response to her situation, the advice given suggests wishing her sister luck in her new relationship, while also acknowledging the complexities of family dynamics. The woman is left grappling with her emotions and the implications of her sister's actions on their family relationships.
