A few thoughts on this...
1. The concern is that most men in your H's shoes won't view what happened as a mistake, they'll look at it as if there was intent. If your H feels this way it poses issues for fixing your relationship and it would be important to be aware of that.
This is a common feeling.
The down side of trying to convince him otherwise, may be a pendulum to the other side, i.e. you had no intent but you are easy, (and I don't think that is true), but its an AWALT mindset, a few breadcrumbs and you will follow the right guy into bed. The right words, the right touches and you can't say no.
Either way his trust in you, and his respect for you takes a hit.
Personally I think continuing down the path of self discovery, healing and growing is the best way to deal with this.
If you are doing it for you, and he can see that independent determination, your words will come to carry more weight when you gently, and kindly speak the truth. It will take some time, and it may make him feel insecure, but you stand to rebuilt some trust and respect that way.
This will also help you resist and call out (gently) any of the manipulation mentioned above, which would prove to be very toxic for you.
But for your own sake you can't keep making destructive choices. So congratulations on your current success. I m glad for you.
I can see the sincerity in what you wrote, and I really wish you well.
