How should I ask?

Anonymous
The guy I am seeing did not make any plans and we meet usually at his or my place. It is usually a spontaneous hang out. But the time we spend together is great. I am okay with it at the beginning and do not want to rush into things. But now after few months, we still mostly hang out in the apartment. I start thinking he did not want anything serious with me, even thought he told me he is not seeing someone earlier. I want to bring this up and ask whether he is only fancy for causal things? Any suggestion on how should I initial the conversation or generally any suggestions?
