<human>: Can you give me a shortened version of the text?

My best friend [17] and I[17] have been friends since we were 6. We're great, we know everything there is to know about each other, we've trusted each other with our heart and souls, and just recently our bodies. 
I started to fall for him 5 years ago, but he had a girlfriend, so I backed off for a long time. 3 years later, they broke up, but by then I had already started dating this guy for about 10 months. 
He admitted to me the other night that we always had bad timing and that he wished I stopped trying to date other guys to replace him. Which confused me, because this guy can't go for a day without a girlfriend. (He just recently stopped dating for a while.) When he said that, I assumed he meant that he wanted to be with me, and we talked about trying out a relationship. His response was always "We'll see" with a cute smile on his face. 
Let's go back a few months: Christmas: I had decided that I wanted to lose my virginity to him, so we had sex. It was great, we were both happy. 
Since then he's been excited about what had happened. He couldn't believe our friendship had been taken to the next level. But what the hell does the "next level" mean? I feel like he doesn't want to date me at all, but it doesn't make any sense if he constantly gives me "I love yous" and "You should be with me" Help?
<bot>: Best friend of 12 years is sending me mixed signals. Possibly playing hard to get, and I'm not sure what to do. I'm in love with him. :/
