Hi,
Firstly I think it is very brave of you to have the courage to come here and post such a well worded post, which is very heartfelt, brings up your issues with your husband without some bitterness (which I think is deserved).
I am also a husband and abdl. I too hid it for many many years from everyone. Including my wife in the first few years. When I finally spoke to her about it,it was hard to do, to admit. She tried to accommodate me and my feelings and I went at it like a bull in a China shop (suddenly able to indulge, I went overboard).
This had a terrible effect on our relationship, and ultimately led to my wife wanting nothing to do with this lifestyle. All my fault.
We are still married, this is a taboo subject and something I can only do alone.
I will not say his actions are good ones, but I will say once you have had to be secretive about something about yourself, it's very hard to break that cycle.
I think you need to discuss this with him, lay it out, without getting angry (but I understand you have every right to be) try to explain to him how this is all making you feel and how he has "gone at this like a bull in a China shop" overwhelmed you with his needs without taking yours into account.
Regarding the secret accounts and A.I. That needs to be confronted, but as I said it's hard not to break the secretive cycle once you have been doing it for years. Not saying his choices are right, but feeling you must hide everything about this is a familiar mindset I recognise.
I hope this helps a little, and maybe as part of your discussion he sees you post and our responses.
I really hope you can work out your differences and have a stronger relationship going forwards.
If you need any support myself and others here would be happy to help if we can
