If s13 knows your wife is having an affair, then you should take him with. He will see what you are doing and it would be good for him to see and understand what is going on. It will get you in the right frame of mind as well. If he doesn't know, not sure you want him seeing it. He will put 2 and 2 together.

HOld on, lis. Just keep holdin on. YOu're doing ok.
