Journaling.... Things continue to go well. My major issue now is fighting all the negative thoughts and visions in my head. <snip> How can i stop these negative thoughts?
You might want to read "The Happiness Trap", I'm reading it right now and it has some awesome techniques for controlling your negative thoughts. In a nutshell it tells you not to follow the conventional wisdom of pushing bad thoughts aside because all that happens is they come back bigger and uglier over and over again. Instead recognize them as what they are- mental images that can do you no personal harm. One of the many techniques they suggest is when those bad thoughts come then give them a name, like "here comes my husband's love affair again" and then sing that name to a tune like Jingle Bells or something. Or if it's an image of say husband with OW, picture that image on a TV set that you control, you can flip the image, turn it backwards, etc. It takes practice, but eventually you see these things as thoughts and images that you can accept for what they are and choose not to react to. Good luck!
