We've been together 17 years, since HS. We have been an exceptionally close couple, and now have a special needs 11month daughter. He was always been faithful until 3 years ago, but now has a history of cheating off and on with the same woman- usually about a year between episodes. I want to forgive him for the sake of my family. We are great together except for the cheating. I believe our daughter needs a loving family.
