Have you tried sleeping pills to help you get through the night? I'm not sure how old your S is and if you'd want to take that route. I also have a very hard time sleeping and have rx pills that help but don't knock me out.
I have done the same thing about OW, thinking about her constantly and what type of contact they've had etc... Don't do it. It does drive you crazy. I put her in the back of my mind as much as possible. I was getting to the point where she was controlling my life because I was thinking about her too much. Completely not worth it. They will get theirs in the end. We have to believe that.
I hope your evening has gotten better since your last post. How old is your S? What things have you been doing with him to keep yourselves busy?
