Hello SoulThinker. I'm so sorry that you're going through this horrible experience. We always seem to find out when everything else is going to shit too and there's a lot to deal with. It's the cherry on the ick sundae.
No one has any magic answers here alas, I wish we did. It sounds like your husband has been cheating on you in some form or other for at least half your marriage. That's your answer to me. I think you'd find out it's probably even earlier than that too. This is who he is. Whether he wants to be this person or not....I don't know. I think if you never found out, and he never got shit for this, he'd probably be this person until his organs give out. Old age and ill health is what puts a stop to this more than anything else. Men (women can do this too but I'll say men because we're focusing on your husband) like this will do it until they drop, even if they are married to beautiful women like models or actresses - the most beautiful women, the most accomplished people, get cheated on and often abandoned. THIS HAS NOTHING TO DO WITH YOU. IT'S NOT ABOUT YOU OR ANY PROBLEM SPECIFIC IN YOUR LIFE. IT'S NOT ABOUT PREGNANCY. It's not about any excuses.....this is the way HE PREFERS TO LIVE IF HE COULD DO IT WITHOUT CONSEQUENCES. We can call it an addiction, which means nothing to me, I think this IS his preferred way of life. What I keep seeing over and over again is that cheaters and faithful people who end up in situations like you do, do not have the same basic ideas or definitions of marriage. The cheater may not even realize that he's like this until he gets into this behavior and keeps getting deeper and deeper. Believe me, most of them ENJOY this lifestyle and would keep doing it - the only problems is if they get caught and they spend too much money, and have problems with their career, etc, over it. But if they can keep it within certain bounds they will keep living like this because it is how they WANT TO LIVE. We keep trying to get them to change, but it's unsuccessful because....this is how they WANT to live.
Oftentimes they want to live a non-monogamous, hyper-sexual life for themselves, but have a spouse who is Tina Truly, who stays at home with the kids and bakes meatloaves, and is kind and lovely and faithful so it's not often mutual. But if you could get him to talk HONESTLY about - or if someone could - about what kind of relationship he ideally would like to have, and how he views specific topics like sex, love, marriage - the more specific the better, I think you would find a basic disconnect between his ideas and feelings on these things and yous. He may not even consciously realize how differently he does view these things, or want to admit it, but I think he does. And how does he acknowledge and admit his preferences AND stay married to you. It's like you're half of his life and the other half is what is encompassed by his cheating life.
Instead of regarding this as a moral failing or some addiction he has, I would view this as his actual lifestyle preference as he's been doing it throughout at least half of your marriage. If this were me, that is how I would talk to him openly about his behavior. The less shame we put onto a topic, the more willing people sometimes are to discuss their true selves. You need to know what this man really is like....I don't think you've ever really known him or that part of him.
That said....as I think this is truly part of who he is and how he wants to live.....to me it comes down to, do you want to accept this. Is this relationship acceptable to you if he cannot or will not change or says he'll change on the surface but you'll keep having D Days in the future, often when you least expect it. If you assume THIS IS HOW HE IS then you can operate from that understanding that this is the package you've got. You can keep it or return to sender but I don't think you can modify it. Maybe once he realizes that you are serious that THIS IS NOT WHAT YOU WANT OR ACCEPT OR WILL TOLERATE....EVER....which basically means separation at minimum and divorce ultimately....he may have to decide HOW HE WANTS TO LIVE GOING FORWARD and make choices of his own. To me, it comes down to what he wants versus what you want. You can't compromise on what you want, it will never make you happy. The same is true for HIM. You can just both come to a recognition that on basic areas of relationship you just don't agree or want the same things and move on from there.
I don't know if my comments are helpful to you, I hope I may give some ideas or insight that may provoke some new thoughts. I tend to accept people AS THEY ARE without hope or insistence on change and then I can either continue on with them, fully or in a limited way....or not at all. But to expect people to change themselves because of what I want, is generally not realistic, in my experience. No matter how much you can see that what they are doing is negative - if it's what they want to do - it's their choice for whatever reason. This is voluntary behavior, not simply compulsions.
