I caught my wife a few nights ago with a "friend" of mine who was supposedly trying to help me through this. I wish my wife would come back anyway. I have no plans on living with it if she comes back, I'm just gonna put it in the past and do my best to forget that terrible scene.
Under no circumstance whatsoever should your "Friend" ever be even a remote part of either of your lives again though, I do know that much.
