Hi, sorry for your situation. Of course you're not crazy, but what made you think you were? Has he implied you're imagining everything and he's really a sober citizen?
If you choose to stay, say another 8 years, you're probably going to need support for yourself as living in a loveless marriage with an A is not an easy path and it will wear you down. Al-anon is for the family and friends of As and has been a life-saver for many people on this forum.
You don't say whether you work or not. I suggest you start preparing for an exit at a time of your own choosing, remembering that alcoholism is usually progressing and can go from bearable to 'get out now' very quickly.
Preparation would be getting a fund of your own together, quietly. You might want to seek some legal advice about where you'd stand. Put together copies of important documents. Keep a diary of anything relevant - credit card statements (if that's where be buys it), the fact that he was passed out on x date, photos, hiding places etc.
None of the above means you leave before you want to, but will be useful if you need to.
I hope it's been helpful for you to post here, and I know you'll get some useful feedback from others. Good luck.
