He still talks to me after sex?

So this guy I’m seeing, I’m not sure if it’s a casual thing.. but we spoke for months, and finally did the deeds.. after the deed he stayed a while with me (chilling and watching tv).. he was telling me how he can’t be in relationships cause he isn’t a relationship guy blah blah.. however I know this guy doesn’t talk to any other girls apart from me, cause never goes out looking. Before he left he hugged me twice, and his messaging me like normal, when I thought he’d just end up ghosting me cause he got what he wants.

He also said how he can’t open up to anyone. I don't know I’ve never done this before.
