Hello Flawed, I'm going to offer a somewhat specific suggestion that I think will help your BH's healing. Go as much as possible into detective mode and do whatever you can to refresh your memory about the details of your A, and use this to flesh out the timeline.
Many betrayed spouses want to know every little detail of an A before they can R. Even the "dirty details". It's a "the devil you know versus the devil you don't" sort of thing. For some it can be easier to recover from something you know than from something your imagination goes wild creating. In addition, there is the "intimacy hole" that an A creates. You shared intimacy with another man that you kept from your BH. This is a way for him to recover that segment of your intimacy. As painful as the details may be, it is less painful than not owning that segment of intimacy.
As you go through this, be patient with him as he asks the same questions over and over. He's trying to come to grips with the magnitude of the betrayal, which is difficult when he doesn’t actually know the magnitude of the betrayal. Answer the same questions over and over, but use the process as a way to try to elicit more memory. Everything you can do to put meat and bones on this and fully describe it as much as possible will hasten that process.
From your BH's thread in JFO, there was a bit of trickle truth from you on these kinds of points. TT is probably the worst thing a WS can do after DDay. Don't TT. They call it “Trickle Truth” but they should call it “Torture Time”. Now is the time to be nakedly, brutally honest with him, even about your heart and its feelings, which I reckon you do recall. If you dug the AP, say so. Honesty helps more than the pain of the details hurt, if you get my meaning.
One of the unique difficulties of A's discovered or disclosed long after the fact is that memories have faded and details are often lost. I gather you weren't on social media at that time, so there wouldn't be that. Do you keep a diary? I reckon not. Young people nowadays rarely keep diaries.
But there are some unique aspects here. You moved to a new city. You must remember when you moved, and when (approximately) you started the retail job where you met the AP. Is the city where you live in a place where there is a marked change in seasons, with a rainy or snowy winter? Your A was in the spring of a year, as I understand it, ending around May?
As I also understand it, you didn't spend the night with the AP. You returned home to your BH each time you had sex with the AP. I would imagine that the walk(s) of shame may be memorable. How did you get home. Taxi? Drive yourself (after partying -- drunk driving, shame on you)? Other? Do you remember the weather in your walk(s) of shame. That is a thing many can recall -- shivering against the cold as you approached your front door, mind racing with what you might say to him if he wakes and asks you where you've been.
Also, I gather there were just a handful of sexual encounters. Like 3 or 4. I find this unusual for a limerent A where you had about 6 months working with the guy, and you had plenty of opportunities because of your late working hours. Why were there so few sexual acts? And, on the flip side, why did you engage in sex the few times it happened, as opposed to all the times you didn't. From the AP's perspective, he was a young dude with a hot new female sex partner. I think he would have had sex with you as often as possible. I reckon you were the limiting decider.
So here is my suggestion. Create bookends, using the first time and the last time.
As to the first time:
When did you start the retail job. How did you get it? What was your first day on the job like? Did you meet the AP in the workplace, at work? If now, where and how did you meet him? What do you remember about him in terms of first impression?
When did he first get onto your radar as a possible sexual partner? What happened for that to occur (I don’t mean “February 17, 2006, I mean “We flirted a bit at work, but after going out drinking with coworkers a few times it was clear there was chemistry between us”)?
When did you first decide you were going to have sex with him and why? By “when” I don’t mean “March 13, 2006”. I mean: “We had talked a lot at work, sort of flirty talk, I knew he was hot for me and I enjoyed the feeling of power over him. One night when we were drinking our talk turned very overtly flirty and sexual. He put his hand on my ass and I liked it. I knew then I was going to have sex with him, but we each had a significant other at home so we had to figure out a time and place to do it.” Or some such.
Where did you drive to? What was that time and place? I gather from other posts that you got into his car and rode with him somewhere. Where did you go first? A bar or club? His home/apartment? A friend’s apartment? A hotel? How did you get home after? Where was your car? Was it cold outside? Wet? What month was it? Was it near any holiday? St. Patrick's Day, perhaps? Mechanics like this often come back with memory review, and this can trigger more memories of the acts.
What were your thoughts/feelings upon returning home that first time? Were you shivering against the cold? Was it still dark? Was your BH still asleep?
As to the last time:
Why was it the last time? The AP was a dude with a hot woman who wanted sex with him. I'm a dude. I know what that’s like. Dudes don't choose to end that. You must have made the decision to end it (or, possibly, his girlfriend found out and confronted him). Had you decided that it would be the last time before the sex occurred? In other words, did you decide to have “one last go”, sort of a bittersweet goodbye? Or did you decide after the sex, something like “I can’t keep on doing this”? There was talk in another post about one non-drinking lunchtime encounter where you went to his home/apartment and did sex stuff in the shower. Was this the last time? Did it occur after your BH had intercepted the suspicious text? When did you get home from that? Was your BH there? If not, when did you see him next? What did you do?
By the way, you should add all of this level of detail to the written timeline of the A.
Once you’ve fleshed out the first and last times, use them as bookends. I gather there was at least one sexual encounter between the first and last. You must be able to at least recall returning home after that sex. Where was the sex? How did you get home? Was it dark? Cold? Raining/snowing? There was mention of you getting walked in on during one session. Where were you when this happened, and why were you having sex there (as opposed to somewhere more private)?
If you go through this, you may be able to recall whether there was one and only one “return home after sex” between the first and last, or more than one. That answers the question that is burning in his heart, which is whether there were 3 times or 4. As I note above, 3 or 4 encounters in context is not very many. Surprisingly few from my perspective, actually. Why were there so few? Was it because there were limited opportunities because each of you had a significant other at home? Or was it because for you the sex was just a way to keep his attention, and you didn’t put a lot of energy into frequent sex with him?
I wish you luck. I do think that the more you can focus on fleshing out a timeline for him with details like this, the quicker you two will heal.
