Please reread the last line of your post. He wants to forget and move on. Ok, time for you to do the same. Most of your post was about her. It might make you feel better to list all the crazy things about her, but it doesn't matter. And please don't lower yourself to dirty looks and dildos in your car--you don't really want to be her do you?
And try not to ask for reassurance ("wanting things to be good"). That kind of statement puts him on the spot to reassure you. My H hated having to reassure me all the time. He wanted me to be confident enough to not need reassurance all the time--and I didn't get any information about OW or any "don't worries".
No more bringing her up, ok? He wants to move on--let him. And move on with him. Don't keep pulling him back into the past. If you should feel threatened by her, then by all means call 911.
Now it is time for the two of you. Work on feeling good about yourself. Keep appreciating him and respecting him. Keep smiling at him.
You're getting really good at this Deb. Keep it up!
