I know how you feel. I started dating this guy "steve" in October a few years ago. I fell totally head over heels for him. He was nice, charming, very handsome, the whole nine yards. We hit it off perfectly. I spent every waking minute that I could spare with him. I lived about 20 minutes away, but worked in the same small town in which he lived, so I would stay with him most nights (and days) and we would do everything together. It was perfect. Until one morning, the following March, when he was telling me over breakfast about the perfect woman he had met. She was so beautiful, smart, funny, yada yada yada, and it WASN'T me. I was devastated. I couldn't even speak. I had no idea what to say. He could see that I was upset and he told me that I had no right to be because we were just "friends with benefits." I had no idea. I couldn't get over it.
It took a while, but the best way I found to deal with that was to just leave it completely. I severed all ties to him and anyone "we" knew that had anything to do with him. It helped me get past it, although it still riles me from time to time. I was 28 at the time and didn't think that that could ever happen because everything seemed so perfect. I may have been wishing and hoping, as you may have been also, but it does get better and easier. It may take a while for you, as it did for me, but trust me, things will start to look up. If you're like me, you'll realize that you deserve someone who will treat you with a little more respect than that. I hope you feel better and cheer up. It can be hard, but you'll pull through with more than you had going into it.
