<human>: I got redirected here from /r/twoxchromsomes, so bare with me. I'm just copying and pasting from the original post. 

So first things first, I had to make an account just to post this. I never actually post anything haha. Also some sex stuff gets mentioned so this might be NSFW

Anyways as the title says, I (21F) started talking to this guy on okcupid in December, but because I got mono we couldn't meet up for a month. We start talking excessively every day - phone calls, texts, pictures etc. I'm falling pretty fast and I know this. Turns out he was too. 

We made things official about 3 weeks ago and today he dumped me. We had agreed to be non monogamous as well...we've both slept around a lot in the past and figured we would be able to maintain a difference between sex and intimacy. However last night (and I apologize for the TMI) we had a threesome with another girl. It went well, until I realized she was staying the night and sleeping with us. I left the room around 2 am crying and he realized something was wrong so we tried to talk it out, but I could barely hold myself together so we decided to talk things out in the morning. 

Here's the fuckup, he knew I had breakfast plans with a friend the next morning, and when I reminded him of this he said it was okay and to text him. So I did after breakfast. He was apparently really hurt that I actually left him to go out that morning and as a result, felt that maybe I wasn't a good fit for him because I "freaked out the night before and left him with just that memory." It scared him apparently.

My head is all over the place and I'll probably edit this post in an hour or so when I can think more coherently, but this was so out of the blue and I'm not handling it well. I'm experiencing huge anxiety, nausea, and I feel kinda dizzy. I was honestly crazy about this guy and he was about me. So yeah. Advice would be appreciated right about now :(

Can you provide a brief overview of the text?
<bot>: First real relationship, pretty sure I love the guy. He definitely loves (loved?) me. I fucked up, he dumped me. How do I move on??
