<human>: Give me a shortened version of the text

Long story short, I developed a friendship with a coworker. He had originally expressed interest in me, and while the interest was mutual, I wasn't in a position to act on anything. Although we both had feelings for each other [read: intense crushes] we were still able to maintain a relationship. We would text / talk / hang out often, simply as friends.  He was very respectful of my situation and never made any advances, although he wanted to.

Fast forward about a year – we no longer work together and end up going out, getting drunk, and sleeping together. We had a great night, but I know how **some**men (and women) are, so I asked him after the encounter if he wanted me to stop talking to him and he told me that he didn't. Since the encounter, he has been very distant (and I'm not clingy, at all).  He takes a couple days to respond to a text, sometimes I won't hear from him for a few days.  Yet, he also sends me texts at various times of the day/night/early morning telling me he misses me and is thinking about me, that I'm awesome/cute etc.

Did he legitimately use me or is he just playing games with me now because he had pursued me for so long originally? I'm a bit confused.  I'm not clingy at all and can separate sex/emotions very well. I value his friendship a lot but I'm not sure if I should just put him in the douche bag book and move on.
<bot>: Slept with "friend". Said friend is now acting slightly distant and seems to be playing games. Should I give up on maintaining the friendship and just put him in the douche bag book?
