Red, don't be surprised by this or feel like you're overreacting, a drama queen, etc. Sure, you opened your mouth when you might have been better advised to keep it shut, but your husband seems to have taken it in stride. Don't discount the power of anniversaries, like coming up to the anniversary of all the affair/divorce stuff. I imagine it's no less potent than the anniversary of a death. My grandmother died in January *years* ago, and every January still throws my mom for a loop. Expect some weird emotional stuff, and cut yourself a break.
