Yes cheating is wrong but that doesn't have anything to do with the relationship itself. Gwen and Duncan worked well together and were best friends in TDA, Gwen was the only one besides formely Courtney that brought out his Heart of Gold. They were able to keep a stable relationship without much fighting for two years so they were already much better than Duncney ever was.
