According to Dr. Schachar, a licensed psychologist, there is no exact time frame for getting over betrayal in a marriage. It is common for emotions to cycle back to the surface for extended periods of time, even after concluding the above-mentioned steps. Dr. Schachar says that, even with the help of a licensed professional, the healing process takes at least a year, so that you and your spouse can go through an entire cycle of holidays and birthdays.
