Regarding the acronyms, I understand your confusion. I don't like them either. I'm going to get quite graphic, so understand it is just to help you understand.
As ALL of us learned, things will never be as they were before. You may want things to go back to the way it was before your WS betrayed you with the AP and turned you into a BS, but it is never going to happen. All the MC and IC in the world will not do that.
The best you can hope for is to get out of infidelity, whether you divorce or stay married, and reach some level of peace, happiness, and acceptance, that is constructive, and be able to move forward in your life without allowing this event to turn you into the very type of person that you were hurt by.
Then, you will be a FBS, not a MH, with an AP, hurting someone else in the same manner.
My FWS, she learned to cheat, from her FOO (parents and their multiple affair partners). She learned to use sex as a weapon of revenge in her relationships, as an escape from reality, as an avoidance from painful thoughts. She had relationships in the past before me where she would get angry with her partner or her prior husband, over whatever reason, and the response to that anger was to go to a bar, party, mall, work, or the gym and literally fuck the first available person whenever and wherever she could (married, single, old enough to be her dad, younger, in a bathroom, in a car, at work, their place, her place, she was also raped 4 times engaging in this risky behavior). She felt powerless in all her relationships. She felt like she had no power even in our marriage, where I went overboard to make sure that I prioritized what she wanted. She felt like she was powerless in her life.
She HATED what her parents had done, what had been done to her in the past, what she had done in the past.
Then, a husband who was not like that, who didn't know the past, 4 children (her choice), dogs, cats, house, living where she wanted to live, working at a job that she wanted part time, mostly full time SAHM (her decision as I made a lot of money regardless of where we lived and she had full agency to decide her work hours, etc.), husband home every weekend and every Thursday.
What did she do?
She became the very thing she hated.
She still FELT powerless, angry without knowing why, overwhelmed, in life, in everything, the only way to escape was to fuck some rando she met and blow it all up. She fucked him in our garage, in our bed , all with the kids at home, in his workplace, where we had our first date (more on that below), in a strangers house, in his house, in a park, and in a random place along the road, and in a church parking lot.
Then she woke up! She didn't know what to do. Her husband was hurt, angry, abandoned, and didn't know what the fuck was going on. At home she'd been treating him like shit, lying all the time, about everything, and he didn't know what to do as nothing made sense. He trusted her completely and had never been in a situation like this. She stopped fucking the other guy, but had to lie, lie, and lie some more to cover it all up, for years and years and hope someone didn't talk. She freaked out periodically, and lied about why. She hated herself. Till 9 years later, on the anniversary of her and her husbands first date, which we always celebrated by going back to that place, but which had become problematic, she couldn't handle it anymore. She broke down and confessed, partially. It took 6 months of MC, and IC, before the truth really started to come out.
You will always be a FBS, there is plenty of time to learn the acronyms, because that is the least of what you must learn in order to not become the very thing that you don't like.
Trust me on that. In the agony of all this, I could have transitioned from a FBS to a MH very easily. I'm male, I work in a profession dominated by women. There is a certain "type" that seems attracted to me and it has been problematic in the past to the point I've had to request administration bar some people from working with me, and require open door meetings with third party present to meet with some clients and vendor reps. Some women coworkers and I've had to go so far as to not get on an elevator with them unless someone else was present. To protect my family, way before the betrayal I experienced, I took great caution, I never go to lunch with another woman outside of a group setting. My wife knew this.
Unfortunately, it didn't keep HER from cheating....
Take what you need, learn at your pace, but stay true to yourself. Also, be aware of your anger, it can destroy you, I'm laying next to a sleeping FWS who found that out the hard way and reached the point of sticking my deer rifle muzzle (unloaded) in her mouth and testing her reach to the trigger before she got the help she needed and truly began to heal.
In the midst of my massive confusion, around the marital problems that my best efforts could not resolve, I started to take personal risks that I should not have.
Understand, we know where you are in your mind, we have ALL been there. Keep true to yourself.
