I can offer some general insights into why a person might continue to keep in touch with their mistress despite being married.
Emotional attachment: Your husband may have developed emotional connections with his mistress, making it difficult for him to completely sever ties.
Guilt and empathy: He might feel guilty about the affair and feel a sense of responsibility towards the mistress, leading him to continue communication to offer emotional support.
Fear of exposure: If the mistress knows sensitive information about your husband or their affair, he might feel compelled to keep in touch to prevent her from revealing it.
Ambiguity about the relationship: Your husband might be unclear about what he wants, torn between two relationships, and unsure of how to move forward.
Lack of closure: He might be hesitant to end the relationship because he hasn't fully resolved his feelings for the mistress or hasn't had closure from the affair.
Hope for the future: Your husband might believe that the relationship with the mistress could evolve into something more meaningful, leading him to keep in touch.
Addiction to the thrill: Some individuals become addicted to the excitement and secrecy of an affair, making it difficult for them to cut ties completely.
It's important to remember that every situation is unique, and these are just general possibilities. If you're dealing with a similar situation, communication and seeking professional help, such as marriage counseling, can be valuable in understanding the underlying issues and working towards a resolution. Trust, open dialogue, and mutual respect are essential in addressing any challenges in a relationship.
