There are folks on SI who didn't use IC/MC (I think Tushnurse may be one of them).
I don't know your story, but if I had to do year 1 again w/o an IC, here are the books/podcasts I'd recommend:
1. "How to Help Your Spouse Heal After Your Affair" by Linda MacDonald. Basics of what a WS should be working on. Quick/easy read in a couple of hours. I'm told it's available free online. A good first book when getting on the rollercoaster. ETA - I read your earlier posts, and would NOT read this if you are NC and not hoping for R.
2. "Not Just Friends" by Shirley Glass. I'd call it the "bible" of infidelity, even if almost 20 years old (and I can't help but wonder how much Glass could have contributed had she not died shortly after publication). ETA - I read your earlier posts, and not sure if it would be very beneficial if you are NC and not hoping for R, though I do believe there are aspects that would be helpful for setting boundaries in a new relationship.
3. Marnie Breecker Interview on Duane Osterlind's "The Addicted Mind" podcast (2 parts). Focus is BS trauma. ETA: this may be helpful despite NC, if no other reason than to put words to many of the thing you are feeling/ are in crisis now... also, bc sounds like your ex may be SA and Breecker/Osterlind (and Minwalla) are all about SA and the trauma of being the BS to an SA.
4. The Helping Couples Heal podcasts. Marnie Breecker and Duane Osterlind got together and started this in 2019. Has 3 episodes with Dr Omar Minwalla, who championed the relational betrayal trauma model for healing. prolly has 8-10 episodes total so far. I found some to be a tad repetitive, but several episodes (esp Minwalla) are excellent. Minwalla really resonates with me. He believes having an A is abusive and an integrity disorder. ETA: Given you are NC / not hoping for R, I'd check out the descriptions for each episode. Some will still resonate, while others may be too focused on the WS or R. Again, if your ex is SA, much of this may really resonate.
5. Rick Hanson's "Resilient". Not about infidelity, but about finding/incorporating joy & gratitude to help heal our trauma. ETA: after seeing you are NC, I'd put this in must read.
6. Bassel Van der Kolk's "The Body Keeps the Score". My "bible" on trauma. History, politics, studies, etc. Intellectually fascinating and emotionally validating. ETA: after seeing you are NC, I'd put this in must read.
7. Everything by Brene Brown. She has an audiobook I got via my electronic library called the Power of Vulnerability that I really loved in that it kind of condenses the gist of her early books. But I've read all her books and listened to just about everything I could get my hands on. Many successfully Rd WS highly recommend her stuff for the WS as well. ETA: after seeing you are NC, I'd put this in must read.
8. Pema Chodron's "When things Fall Apart". TBH, I have some trouble finishing her books. I got through about 1/2 of this and did benefit from it. Many on SI love her stuff (including successful WS)
9. Janis Spring's "How Can I Forgive You". A book I now recommend to everyone - whether they've experienced infidelity or not. A good touchstone for thinking about acceptance and forgiveness in all parts of life. Has a chapter for the "offending party" (aka WS, as the book is not "about" infidelity). ETA: after seeing you are NC, I'd put this in must read.
10. Help.Her.Heal by Carol J Sheets. Sheets is a CSAT who has a podcast. This is for the WAYWARDs, not the BS. It's a workbook designed to help a WS cultivate empathy. My WH's CSAT recommeded it. I read it and it looked good from my perspective. Not needed if you have decided against R.
11. ETA: I'd add "Healing Rage" by Ruth King. Maybe low on the list. My trauma IC recommended it and I loved it. It's not about infidelity, but about women's anger.
12. ETA: I'd also add "Journey from Abandonment to Healing" by Susan Anderson as a must read. Given you are not hoping for R, this one might really resonate with you.
I may also consider reading up on codependence (starting with Melodie Beatty's "The New Codependence" ), but only after checking out the Breecker/Osterlind podcasts. Many BS may be labeled codependent bc their trauma response looks similar to CoD. I had some CoD issues prior to dday, so I needed to reacquaint myself with this stuff. You may not be in this boat.
Infidelity books I would never recommend:
1. Anything by Esther Perel
2. Janis Spring's "After the Affair". I loved her book on forgiveness, but HATED her book on infidelity. I found a ton of it to be outright or subliminal BS blaming. Sorry, but I do not ascribe to the idea of my behavior making my WH "vulnerable" to an A, any more than I believe my WH's behavior made me "vulnerable" to shoplifting or any other dishonest behavior. Some folks loved it. She's got some pages for the WS about when they can address pre-dday problems in the M... but NOTHING on when a BS may want to address that shit. That's the kind of stuff that makes my blood boil. It may resonate better with a truly remorseful WS who "gets it" and is working to change.
3. Anything by Mira Kirshenbaum. Same thing on BS blaming and "vulnerability" to an A, coupled with a lot of excusing WS behavior. Not to say an EA isn't painful. Not saying EA not a betrayal. Not saying a BS to an EA is not traumatized & hurt. But she somehow paints herself as an expert on PAs after experiencing an EA by her WH. I came close to throwing my ipad across the room while reading one of her books. The fact that one of her books is titled "when good people have affairs" should say enough.
3. Buying/reading all the books on infidelity. I have a >2ft tall stack of infidelity books (and that's the ones I had to buy - my library card was chock FULL of infidelity stuff for all of year 1 and some of year 2). I'm just now thinking I should sell them as a "lot" on ebay! Some are better than others. Some will validate the pain and anxiety, etc. But overall, I'd stop with the infidelity stuff in the "recommend" list. I wasted a lot of time reading all I could get my hands on. I don't think it helped a bit. That time would have been better spent practicing some mindfulness, gratitude, meditation, and Hanson's HEAL steps.
