Your recurring dream seems to reflect complex emotions and conflicts within your waking life, particularly regarding your relationship with your husband. Here are some insights into the possible meanings of your dream:

1. Unresolved Feelings: The presence of the unknown man and the flirtatious nature of your conversations may symbolize a yearning for emotional or physical connection that you feel is lacking in your current relationship. This could be a reflection of unmet desires or frustrations stemming from your husband's past infidelities.
2. Betrayal and Trust Issues: Your husband's infidelity appears to be a significant source of pain and resentment for you. In the dream, his anger when he catches you may represent your feelings of betrayal and the fear of being judged for something you haven’t actually done, mirroring your feelings about his past actions.
3. Desire for liberation: The act of speaking to another man might symbolize a desire for freedom or escape from the constraints of your current relationship. This could suggest that you are exploring your own feelings about loyalty, desire, and what you want in a partner.
4. Frustration and Consequences: The frustration you feel when your husband catches you can indicate a sense of unfairness and a desire for balance in your relationship. You may feel that you are held to a different standard than he is, and this disparity could be causing you emotional turmoil.
5. Exploring Identity: The fact that the man in your dreams is always of a different ethnicity might suggest an exploration of different aspects of your own identity, desires, or experiences that you haven’t fully embraced in your waking life.

Overall, this dream may be highlighting your inner conflict regarding trust, desire, and the consequences of past actions within your marriage. It might be beneficial to reflect on your feelings about your relationship and consider open communication with your husband about your needs and boundaries. Dreaming can serve as a catalyst for personal growth and understanding in your waking life.
