our marriage is in a better place than it’s ever been
ThisGuy, your pain is evident in your words. 13 years is a long time to be carrying so much pain and suspicion. You say your marriage is better than ever, but it doesn't sound like that isn't what you're feeling in you heart. Maybe it's what you think you *should* be feeling based on external factors, like how often you and she have sex, or how well she is following your rules, or how many years have passed since DDay, but if you truly felt that things were better than ever, I don't think you'd have written this post.
I'm afraid I don't have any advice for how you get past your 4 key issues. I tried reconciliation for 2.5 years, and in the end, I realized that there were too many things I couldn't get past, so I decided to walk away. My life will be my own after the divorce is done (except when we have to deal with kid stuff), and that's the only thing that allows me to let the pain go (though it is still a struggle at times).
I'm sorry you're having an especially tough time right now - maybe the feelings are worse because of the holidays, or this time of year is close to DDay or some other high-emotion event for you? Did something happen that caused you to make this post, or do you feel like this all the time? If it's the latter, maybe you have to admit that you aren't going to get over this.
It took me a while to accept that the cheating and subsequent lying were deal breakers for me. I'm certainly not the only one who has struggled with this (and wanting R to succeed) and eventually arrived at a point where we had to walk away for everyone's good. Not all of us are cut from the same cloth, and not everyone can get past infidelity.
