What follows is JMO.
I've stayed away from this thread because the the premise bothers me. As I've written, you don't heal your BS; your BS heals himself.
I've been posting on a thread of your H's about the Drama Triangle. That often goes along with co-dependence, and this thread seems to me to stem from co-d. That's an observation more than a criticism.
The antidote to both DTs and co-d is getting authentic. You say that's your aim. One of my aims with this post is to confirm for you that you're on the right track.
In general I read a lot of comparative words in your posts - doing something better, for example - and I read 'try.' I suggest dropping 'try,' because it really means 'put in effort and fail.' As Yoda said, 'Do or don't do.' You can't be perfect. You'll fail sometimes no matter what. You can learn from failures - but we're all responsible for the results we get, not for our effort.
Comparisons are similar to 'try'. I think you may find a lot more success if, for example, you commit to a new behavior than if you commit to 'getting better at the new behavior.'
Do or don't do. And if you commit to doing something and fail something important enough, pick yourself up and start over. No one's perfect. No one has the right to expect perfection of himself or of anyone else.
Some comments on statements that stick in my mind.
It almost feels like because I “got away” with lying for 12 years, that I shouldn’t “get away” with anything that’s hurtful ever again.
So did you confess to be punished? Did you confess as a way of getting someone to force you to stop lying?
The thing is, no one can force another person to stop lying. A person who wants to do that has to decide to stop lying. I get that you want to tell the truth, but I'm not sure that you've decided to.
That's a big step. It's really hard to stop lying when it's a habit. You have to make the decision, accept that you might backslide, accept that you'll have to endure the consequences of backsliding, accept that you'll have to restart the new behavior a number of times - but you can do it.
You owe it to your H. You owe it to other people. But above all, you owe it to yourself - telling the truth will make your life much easier.
What I didn't write is how much I am working to also understand my BS.
My initial reaction is: Stop. Just Stop.
To be authentic, you need to focus on yourself - your thoughts, feelings, behaviors, wants, don't-wants, etc. You take care of you.
Let your H take care of his own thoughts, feelings, behaviors, wants, don't-wants, etc. If he has difficulty with that, it's his difficulty, his problem to solve.
IMO, R is on the table most effectively if there's a good match between WS's and BS's wants and don't-wants. I'd hate my W's desires to be identical to mine, but there has to be a significant overlap, IMO.
To find if you and your H fit, you both need to speak honestly about yourselves, from your hearts, irrespective of what the outcome will be.
Speak from your heart. Listen with your heart as well as your ears and 'computer.' See below.
I think I do have a tendency to make assumptions about what he's thinking and feeling that aren't about him.
Of course. That's why I say listen with heart, ears, and 'computer.' You have to distinguish between what you understand and think you understand. That means asking questions for clarity, even if you're afraid your H will get angry.
Good luck to both of you.
