How can a woman obtain a divorce from her husband who claims to be assisting his female colleague at work financially and personally, while she feels he is in a relationship with her, and she rejects this situation?

If the husband's relationship with his female colleague adheres to Islamic guidelines, then the wife is not permitted to request a divorce, and his assisting her out of need is not forbidden. However, if the relationship is illicit, then he must first be advised and admonished. If he persists and advice proves futile, then the wife may seek a divorce as a last resort, while considering its potential consequences, as it may not be in her best interest. Specialists should be consulted regarding legal procedures.
