You know, I was honestly considering cancelling our internet service and throwing the computers away after this, but i realized that it is not the internet that is the problem. If someone is wanting to "find someone else" or reconnect to old flames to find out "what if" then there is an existing issue in the relationship (OR PERSON!) and it's going to happen anyway.
I DO understand that the internet and FB in particular make it SOOOOO much easier to accomplish, but, as I've always been told, it is just a tool. Tools are not inherently bad or good, it depends on how they are used.
I really feel for what you are going through as well. Stay strong and be the shining example for your kids. When all else is stripped away, THEY are the only ones that matter!
I busted my W one night. I had stayed up in the livingroom reading and when I went down the hall to turn off my D's light, I saw my W had her cell in bed...at 4:30 AM and tried to hide it under the covers when she saw me. I thought something was going on prior to that because she was staying up ALL night typing on the computer and puting up a solitaire game when I walked by as well as NEVER letting her cell out of her grasp (sleeping with it, showering with it, etc).
Good luck and stay strong!
