So happy for you, Ace. The Glass book was one of the first books we read together. It took us a long time to get through it, though. I had to set aside at times because it would trigger me. But 2 years out now, I consider Shirley Glass a saint.
Our MC suggested that when we were ready, the next book to read is Hold Me Tight. We had to set it aside a few times, too, but eventually picked it up again when we were ready. It is a good next step book, IMO, but sometimes you have to take these books very, very slowly.
My H read the How to Help Your Betrayed Spouse Recover book. He ended up reading it a second time several months later and discovered more insights. I guess we're learning that these books need to be revisited as we grow through this process.
Blessings on you and your R.
