Flirting with someone outside of your committed relationship, regardless of their appearance, is generally not considered appropriate or respectful. Trust, loyalty, and emotional commitment are essential components of a healthy relationship. Engaging in flirtatious behavior with someone else can be hurtful and damaging to the trust between partners.
If you find yourself attracted to someone else, it's essential to communicate openly and honestly with your partner about your feelings and work together to address any issues within your relationship. Open communication and understanding are crucial for maintaining a strong and healthy relationship.
