I don't know

So me and this guy have been messing around for a while now and this past weekend we hung out and did stuff and after we were done he told me has a girlfriend now. For a few seconds I felt bad but then i didn't because I liked him for a while but I just got over it. I don't know does that sound a little hoeish? If she finds out I'm not taking the blame for this because he was the one that asked me for sex first. So what should I do because I don't feel bad about it.
