<human>: Can you succinctly summarize the text in 1-3 sentences?

Long story short, I lost my virginity a few weeks ago to a guy who was explicitly a casual fling. We still talk everyday, and he calls me up when he's drunk (rare), and when he does, he talks to me as if this whole thing isn't so casual I guess you could say. When he's sober, it's a different story, and I feel somewhat stupid still talking to him as much as I do. I really like him though, but I feel like it's because he's giving me the kind of attention I've never had. 

 I know what's going on, but I still have my stupid desires and unrealistic ideas of what could happen. Can someone be blunt with me and tell me exactly what I'm not understanding for me to stop.
<bot>: Had sex for first time, getting too attached to casual fling, and don't know how to come to terms with reality.
