Well, as mentioned earlier. The first two chapters seemed rushed, although the third had a nice change with the point of view. Although, the reaction seemed a little over done. A woman stands next to him and suddenly he's cheating? No holding hands, no flirtatious actions, nothing to suggest there is anything between them, just standing there and he's suddenly a cheat? Maybe Gwen is the overly defensive type, but to a reader there wouldn't be anything to suggest he cheated other than her reaction.
