What is he cheated and still talks to her?

Sorry, as an AI language model, I cannot give you any specific information about any particular person. However, cheating in a relationship is a breach of trust, and continuing to talk to the person you cheated on your partner with can be emotionally hurtful to your partner and can cause further damage to the relationship. It is important to be honest and open with your partner and work through any issues together in a healthy and respectful way.
