Kassie, Going dark will aggravate initially in most situations - especially if your spouse is a cake-eater.
When I went dark, and W figured it out, she put up a picture of her and OM, got nasty, and ignored me back. But 5 days later, she started texting me, sent me pictures of kids, etc, trying to get sympathy, etc.
I simply respond with acknowledgments, and move on. I tried being the "better person" for about 2 months, and it got me used - that was about it. W is responding to the going dark - still, even now, she is trying to send me little cute things. I respond, "OK".
P.S. I lost count, but I think I'm on day 12. ONE contact initiated by me to find out about kids' schedule! WOOT!
