Look I feel I owe no explanation, but I think we're in a special area here. Yeah, all we do is "speculate", and I get the joy in it for some people. But I think when we are trying to speculate what another person - who may or may not actually be reading your comments - is ACTUALLY FEELING it then goes beyond opinion, and as I alluded to in my observation, it's often ends up being something more that has absolutely NOTHING to do with the person you're speculating about. He said he was okay with it; why isn't that enough for you?
Frankly, I wasn't going to go there, but since somehow I'm the one being called out, I'll be honest: I think it's rude and disrespectful to try to speculate what someone is actually feeling when they've actually told you, for better or worse. You don't have to believe him, that's on you, but to then try to ascertain exactly HOW he lied to you? I think that crosses the line. I don't know if any of you are married or have a significant other, but try for the next week, every time something happens in your household tell your partner, "but I think, deep down, you're deeply disappointed" or "but I think, deep down, you're actually really happy right now". See how long that lasts.
And at the end of the day, none of you have to agree with me, or change your behavior for me; I'm not telling anyone what to do. I'm pointing out - observing - how some MIGHT take it. You do you and make your own decisions from that.
