Bubbly, based on what I am hearing, I think in a sense your brain is telling you to get out. The signs are there... they HAVE been there for some time. But just as for many of us, the pain of going through the divorce/separation and all of the abundant changes and turmoil it brings can "lock you up" and cause you to do nothing.
You basically have two choices. One is to wait until things get so bad that you basically "blow up" and the break-up becomes sudden, toxic and bitter. The other is to tell him and confront things head on, NOW. If he's willing to change some of his behaviors, and if you're willing to give that a try, fine. Get some marital counseling for the two of you. If not, then you can begin to transition out of the marriage and hopefully it will now be at a point where you can call it quits without "spiraling downward" to become more bitter and depressed.
Wishing you the best :)
