Did it with a closeted bi/straight guy. He's not talking to me anymore. Advice? What should I do?

I had a straight friend (not close) who I hung out with a few times. He would sometimes flirt with me on text, subtly, but I would blow it off, knowing he was straight and had a girlfriend. However, recently, we went out to dinner, and he asked me to give him a massage at his apartment. Once reaching his apartment (we were alone), he stripped down, told me to get my clothes off. My wildest dream came true! I was very horny, but managed to control it, gave him a massage (on top of him). After the massage, he asked if he could fuck me. He fucked me, but only for a few minutes, then he pulled out with a look of disgust on his face (although that could've been misinterpreted as exhaustion). I don't think he cummed in me. He didn't use a condom (didn't have any). I asked what was wrong, and he denied anything was wrong. He said the massage felt good. He kept insisting I didn't tell anyone about what happened. I kept reassuring him I wouldn't. He said he was secretly bi. I then went home, texted him that I arrived home safely (he asked me to do so), and haven't heard back from him at all. He was all "over me" on text before the incident happened.Did I do anything wrong? I'm confused and somewhat hurt. Thanks for the advice!
