marriedaliar - of course you can't understand your husband. Your're a normal, decent person. He's not. I think he's a sadist, and possibly a psychopath. These people hide themselves very well until they get you under their power, if they can. One of their favorite tactics is to isolate their victims. They try to do this physically if they can - you'd be amazed at how many stories of this type of unfaithful moving their spouse victim to some place where they don't have contacts. Often they make is as a business thing or improved lifestyle - oh, I have these business ops here, we'll make a lot of money, we'll live in the country, it will only be temporary, etc.....and the betrayed spouse becomes socially and often financially isolated. THIS IS A DELIBERATE TACTIC. It puts the victim (and don't take this as a disparaging term - it could be any of us in your shoes) at their mercy. They may even try to make you think it was YOUR idea rather than theirs They are very cunning and manipulative. This is not like the ordinary wayward spouse who falls into an affair for various reasons....it's a deliberate plan they come up with to get you under their thumb as a victim. And then they use psychological tactics of belittling, gaslighting, subtle insults, making you doubt yourself - it's a whole program of psychological disintegration - to get you completely under their control
You can't really understand this because.....then you'd be a sicko too. Normal people can't even comprehend that there ARE people like this and this is what they are doing. It's hard to even explain it because....he seems like such a nice man. He's got a good act. Your parents should have told you right from the start that they didn't like him but people are afraid to say these things.
So, that's really my explanation for this behavior. Some of them may study these tactics, but I think much of it is innate - they just seem to know how to do this stuff. One of the tactics is to do things intermittently, there's a name for this thing in psychology, but I forget. They'll be nice to you and then you think he's not so bad, he does love me, blah blah, and then they'll do something rotten or hurtful so they try to switch it up. This is NOT the common type of wayward spouse, by the way - there are quite a few, I think our modern age tends to produce them, but your husband sounds like an extreme case. Obviously the whole thing about the Stoics is just bullshit to give him a built in excuse and explanation for his behavior. I doubt if any of the Stoics actually advocated devastating your poor wife and/or family over your adultery. In fact, I think they'd be against adultery because it disrupts the social order and it shows a lack of self control. Stoics, to my understanding, were more about having self control and discipline to meet the conditions that were thrown at you rather than disrupting marriages and the social order YOURSELF. He's misusing their philosophy.
At any rate, DON'T WORRY ABOUT WHAT HE'S LIKE OR WHY HE'S DOING THIS. HE'S A PSYCHOPATH - AND I DO MEAN THAT. You can predict or be aware of some patterns in behavior as I've explained, but you can't really understand it because they're not like the rest of us. They're wired differently. Don't waste time trying to understand this. YOU CAN'T.
If you want to see this in action, the best example that I know is the Ingrid Bergman, Charles Boyer movie GASLIGHT - it came out in the early 40s, if I recall correctly, and it really shows the psycho job a determined person can do to another, for reasons the poor wife can't even imagine. It's set in the Victorian era but it still applies today and holds up very well. DO NOT WATCH THIS WITH HIM. In fact, let him know as little as possible about what you are doing and do not hesitate to lie to him. He's not your friend, he's actually an enemy who wants you under his heel.
I assume you're from the US? If you need funds, the US embassy might be able to help you get back to the US. I would return back to your homeland if you can, and initiate divorce from there. I think you should work on a divorce, DO NOT EVEN CONSIDER RECONCILING, and be careful not to get pregnant. Do what you can in secret as much as possible and don't discuss his bullshit ideas with him. Just smile pleasantly, be as pleasant as you can, but perhaps hide behind not feeling physically well. And then plan your escape. The only way to deal with these people is to escape them. Try to keep as much as you want to or planning as secret as possible, don't leave things out where he can see them and pass code everything. Try to have your own money that he does not have access to. But I would go back to your home country as soon as you can even if you have to leave some things behind.
I'm sure you think I'm exaggerating....but I'm not. He's a classic case. Also, if he even seems to be getting at all physically abusive or violent with you, get out right away. Do not trust this man. Focus on escape and separating your lives and becoming independent again.
