I am sorry to hear about your husband’s affair. Sorting through all of the feelings that arise from a spouse cheating can be quite traumatizing. Since you say he broke it off with your sister, I assume that means you are giving your marriage another go? If so, I would recommend you taking him back or giving it another go contingent on him going to marriage counseling with you.
Through counseling you need to determine the reason for the affair and whether or not you should even be trying to save your marriage. You need to discuss whether this was long term with an emotional component or if it was more sexual. If you and your husband want to make the marriage work, you will likely need to make some changes or this might just happen again. A marriage counselor can help you with structure, problem solving and conflict resolution.
Ultimately though you both need to truly want to make the marriage work. If your husband is just saying this to appease you because he was caught, then you might want to consider other options. Since you want this feeling to leave, you should get some individual therapy to help resolve these feelings. There is no magic cure though, so no matter what you do, it may take some time for true healing.
Best of luck,
