I think you need to find a good counselor that will help you asap.
Don't think about what your h is with as they always affair down and choose the opposite of their wives. You can ask many of us here and we will all tell you the same thing.
It is the thrill of the chase and infatuation--it does and will wear off.
With regard to your job--you need someone to give you a gentle push so that you will stop procrastinating.
Honestly, I would attempt to find a C who will help you with that and with regard to your husband/marriage.
