You cannot tell the age of a participant in a virtual reality video game. I do not ever play video games, but I am familiar enough with the virtual reality as an objective observer to tell you that you cannot be sure of the age of a participant. You can only know how the participant represents herself.

Just as make this error in judgment not questioning the representations of the woman in a video game, you might also make errors in judgment assigning blame solely to yourself for a wide variety of things for which you and the ex wife were jointly responsible - see s4ndm4n2006's post immediately above.
