<human>: Condense the text into a few key points

My ex and I were together for 3 years and 4 months. Really screwed up relationship. We have been broken up for almost 4 months now, but early on there were some sexual slip-ups, and since then we have been attempting no contact (I say attempting because some failures have happened via email). 

I have always known my ex's username. Tonight I had a few beers and I was missing him a lot. Started browsing his posting history (I had only done this maybe once before, when we were dating)... I just wanted to laugh at his dumb jokes, look at his pictures, etc. Then I hit some comments on r/gonewild posts. Okay, fine... obviously his sex drive isn't stopping with my absence. Breathe and move on.

Find a fucking Scumbag Stacy post about me (from 1 month ago...) just absolutely trying to tear me apart. Luckily most people saw through the bullshit and it was downvoted a lot, but it still HURTS. I'm crying and I feel like I'm right back at the beginning of the breakup. I responded irrationally, without even pausing to think once I saw it, and sent him an email saying how much I hate him. I guess I just want advice on what to do now. I know he will be emailing me back, but I'm trying to keep NO CONTACT and I just seriously fucked that up, in all sorts of ways.
<bot>: Fucked up NC by stalking my ex's reddit account, found some hurtful stuff, and emailed him about it. Now what?
