I wonder if the author ever emails one of the two friends about the other. It's unfair if only one side of the private emails gets opened, but the other stays hidden. Also, given that presumably you're still friends after this incident, who cares? A single email is a ridiculously small facet of a person to base an opinion off of.
And if you weren't friends but just colleagues, who cares? You've just learned an important bit of information: your colleagues don't approve of your expenditures. This will help you plan your future. Take it and learn. More information is hardly ever bad.
