Cheated on. :(

Do you think it's possible to forgive someone and move on from a partner cheating? If you have been through this please let me know how u got through it. This is not for people who have been cheated on multiple times, of for those that have been with someone for a small amount of time before there partner cheated. This is for people in serious relationships where they have been togather for years and there was one mistake. Thanks.
