You seem to be more delusional than it first seemed, @Trustisanissue .
A fact is something that is irrefutable because it has empirical evidence or information that supports its validity instead of theories and logics. Ex 1 cheated. That is a fact. Ex 2 cheated, that too. Anyone in a relationship has the potential to cheat. That is a fact, also. And that is pretty much the extent of your facts. While I wouldn't debate number of conversations or arguments, the sad reality is that you got one crucial statement wrong:
"I'm not doing anything to him. That's a fact." - You are. You are actively berating/frustrating a person for something he didn't do, better yet: For things someone else (factually) did. That is something. Not nothing.
Let's lean on facts that you seem to enjoy a lot. You said it yourself: "He got upset... He found it upsetting...he found it hard to hear". These are factually up there in your post. So turns out, you ARE doing something to him, well how about that...
Do you know what's making it extra sad? Just a couple of comments ago you say "you don't think he could either". And YET, you spiral into these things. Does that scream "healthy" to you? Don't know what to tell you, the vast majority of everyone who have been commenting here say that it is actually pretty horrible what you are doing, we come from different walks of life, different ages, backgrounds, sexuality and upbringing...and yet, we (vast majority) try to make you see reason, and make you understand that it is not fair to him, what you are doing, it is a form of abuse.
And yet, you are just sitting here, reading through all these comments and say stuff like - Nothing is wrong with me just for acknowledging the possibility. Yes, but you don't seem to grasp that line that separate a reasonable understanding of something vs letting it shape your behaviour and mindset.
People in a healthy relationship should be able to share, yes. But they should "upset" these things.
"Your example has no parallel with this whatsoever. That's a fact!" - Ah, but see, this is where it becomes blatantly obvious that you don't get it, you truly don't get it. Want to bet that most people here will see the parallel? The fact that you don't just supports why you are in this situation to begin with.
You said it yourself - you don't understand how to "get to a better place mentally on this one". That is why people here suggested therapy. You have such strong trust issues that you don't even see it as a problem. That is a spectacular height, let me tell you. IT IS IN YOUR USERNAME, dammit. TRUST is an issue. Well for a healthy, functioning relationship, it shouldn't. It cannot function without it.
