I think you should do as he says, delete the email and do not ask about the meaning behind it. Besides the fact the OW is a immoral b!^@h, there are countless other possibilities about what is causing him to be f$%^ed with her. He needs help. But I think he needs to help himself at this point. I know that you would like to be there for him. But what good would it do for you to get sucked back into the drama and the roller coaster of emotions that it brings? Try as best you can not to dwell on this email or seeing him this weekend, it will only drive you crazy.
