It is impossible for me to know for certain what this woman's intentions or future actions will be regarding her marriage.
Entering a relationship with someone who is already married is a complex situation with numerous ethical and moral considerations. It's important to recognize that being involved with a married person can lead to significant emotional challenges for all parties involved. Additionally, there may be legal and social consequences to consider.
If you find yourself in this situation, it's essential to have open and honest communication with the person involved. Discuss your feelings and concerns with her and make sure you both understand each other's expectations and boundaries. Keep in mind that she may have various reasons for not leaving her husband, and those reasons may not necessarily be related to you or the strength of your relationship.
Ultimately, it's crucial to prioritize your well-being and emotional health. If the circumstances of the relationship are causing you distress or discomfort, it may be necessary to reevaluate the situation and consider what is best for you in the long term. Seeking guidance from a therapist or counselor can also be beneficial to help you navigate through such complex emotional situations.
