leafields, I'm not trying to sugar-coat anything nor am I trying to make you feel better with this next statement: You seem to have your shit together. The tone of your posts are quite different from mine when I started posting in JFO. I was a complete mess, you seem to be taking this all rather more centeredly(?) than I did. I'm adjusting my what-advice-does-she-need-now meter, hope I get it right.
Humans have goals and we use strategies to get to them. We have a thing called a "personal narrative" (you can google that) that is, basically, our story of our lives to ourselves to explain how we got here. Having your personal narrative broken, or shown to be based on someone else's lies (a betrayal) is a mentally painful thing. As you are no doubt experiencing. We have another thing called "agency", which is best described as deciding what to do and how to do it based upon having the most complete information possible about a situation. Your WH took your agency when he started lying to you, and having your agency intentionally stolen is another betrayal that also causes mental pain.
Here on SI we have a generally agreed upon common goal of "Getting out of infidelity." That doesn't mean the site favors D over R, nor does it exactly mean get away from cheating, although that's part of it. Getting out of infidelity is more about changing to live authentically and, if your WH can't change to live authentically so that you can both "get out of infidelity (betrayal)" _then_ we take that as a pretty clear reason to D instead of R.
I hope that you take this next bit of my post as the helpful, gentle, constructive, criticism that I intend it to be. Take a deep breath and be open to genuinely _thinking_ about the situation that you're in. Here we go.
I understand fully that you're hurt and mad and angry and betrayed and that you love who your WH was and that you're confused and sad and, and, and... That's The Emotional Rollercoaster. You'll feel like a rider on the wildest emotional ride that you've ever experienced and you'll also likely feel crazy and that's okay, we've all done it. It gets better with time and self-care.
With that said, I'll quote you:
He doesn't like confrontation or saying no.
I'm taking this as a given, then. No questions about it. Lots of people like to avoid confrontation and most people try to give answers that seem to be what the questioner wants to hear. People also blameshift to feel better about themselves.
I told WH that his A was SICK & he had to do IC for THAT before I'd consider MC.
Remember the goals and strategies mention, above in this post? What was your goal that you chose this communication strategy with him? To hurt him? To relieve your hurt? To convey information? To extract information?
The way we communicate shapes the receiver's reply. If I say to you, "That's sick!", that's different than, "There're a societal norm against cheating and incest" and both are different than your question of, "Why?"
If he's conflict avoidant then making these sorts of emotional, judgment-laden statements is a good way to shut him down. You might even have wanted that, you might have needed to get it off of your chest. You can heap shame upon him -but- shame is a very selfish, personally-grounded response. I think there are youtube videos from Brene Brown about shame that are pretty good.
In general, making statements about someone's behavior shuts them down. Asking questions is a good strategy if your goal is to extract information. Keep asking, "why", "how", "who", "what", "when", "where" questions to keep the conversation going.
If you can even stand to have a conversation right now, I get it.
BTW, an aside almost, item 11 in the BS FAQ in The Healing Library is The 180. You can use it to distance yourself a bit from the situation to think more clearly -and- using it will shake up the WS because they'll see that they're losing control of the situation. Watch their reactions to The 180, they'll often use methods to try to gain back control of the situation.
Asked him, "Why?" & his answer...wait for it... was "I don't know." (Sound familiar?) I told him that was BS & he was lying to me.
What was your goal? To test what the answer to be? To genuinely extract his "why"?
His answer, "I don't know," was likely very true for him right at the moment. I also noted that he tried to blameshift his behavior onto her, which reveals another problem that he has:
Boundaries. He has poor boundaries in his interactions with other people. Conflict avoiders are often like that. His "not saying, 'No'" likely gets him into trouble. Good boundaries are more like:
Random Woman: Hey, you're cute.
devotedman: Thanks.
RW: Let's get together some time, honey!
dm: Let's not and say we didn't. (Then leaves.)
Back to goals and strategies. His first "whys" are going to be very simple and very wrong. Here's why: You know how something lost is always in the last place you look? That's because _you_ _stop_ _looking_ once you've found it. Answers are like that, too, in that _we_ _stop_ _looking_ once we find the first answer that satisfies our mindset.
Taking that and the boundaries (above), if your conversational goal was to extract information and your strategy was asking questions you might get something more like:
mrs. lf: Why?
mr. lf: I don't know. She wanted to.
mrs. lf: Did you say No? (forget the "I don't know", conversational filler and a diversion, a deflection, a try to get the conversation to stop even if it pisses you off, maybe especially if it pisses you off and you leave him alone. Goals can be very short-sighted.)
mr. lf: She pushed me.
mrs. lf: Did you say no?
mr. lf: Yes. (a deflection, and an attempt to guess what answer will satisfy the questioner and cause the difficult conversation to end. His goals are different than yours.)
mrs. lf: Obviously not or we would not be having this conversation. We'd be having the conversation where you told me about it and then we had another coffee, but instead we're having _this_ conversation. Why did you say Yes?
mr. lf: ...
Granted, this conversation is made up in my head, but (and this might be one of those "buts" that makes everything I say next okay) I did it to illustrate some principles. If you want the deeper conversation then keep asking the "what, how, when, why, where" questions and point out the logical inconsistencies.
I realize that you might not be emotionally ready for those sorts of conversations, yet.
leafields, are you having any specific emotional reactions that we can help with, right now? Don't forget to exercise, it works off stress and pent-up energy and releases chemicals that help you to feel better.
Do think about re-reading your thread from the start from time to time. As time passes you'll get different ideas from the posts, like watching a movie twice or three times lets you see different things in the movie.
