I can’t give you that answer. I wonder if you two have done the work to heal. If you have been seeing a counselor and you have talked or are talking it out I would say let it run its course. I think regardless of who cheated meaning this goes for women and men, the person who is holding the cards is usually the one who has been cheated. You can’t determine how long that person grieves this betrayal. That is what it is your husband feels betrayed. Men are also wired differently they could be a cheater but don’t get over being cheated on. Women also cheats for other reasons than simply sex. So you need to figure out the reason that you cheated and if that reasoning has been resolved. If not you may find you doing it again. So I would seek counseling in addition to martial counseling. However you also aren’t trapped into your marriage. If its worth to go through this pain you may find that you and your husband to be stronger. But it has to be both wanting it. If you find that only you are interested in making it right, you have to make that decision. The only thing is that counseling will help so that you don’t take the same patterns into another relationship. I remember my husband going to counseling and our counselor let us know it’s not an easy fix. It wasn’t about cheating but the same principle applies. Counseling isn’t a fix. It helps you weed out your feelings and helps you determine your threshold for love and work. I wish you peace as you continue but ONLY you can determine how long you should work or if you should throw in the towel. I would say counseling is the best way to go about it to start the journey.
