Normal after a one night stand?

S

I hooked up with a coworker earlier this week after a night out with others. The whole time he was by my side and wouldn’t leave me. After, we cuddled, hooked up, cuddled more, then napped before I had to leave. We said goodbye and that was that. He never texted me the day after, so I texted him a few days later asking if he made it to where he had to go okay. We texted a little and he said he was super thankful that I took care of him and that he owes me. I don’t see him every day at work...sometimes not every week. I know he has that player mentality and likes to go out a lot. Does this seem like we’re cool? I also am so terrified for some reason that group I went out with won’t want to invite me to go out again because of this or bc it’ll be awk? Idk I worry a lot ...
