Is he hinting at something?

There is this guy I've been casually dating with. We are not exclusive yet. We both confessed that we love each other. I want to ask him to be exclusive and I feel like he is hinting at that too. He's been joking of us getting married and 2 days ago he seriously asked me "shall we get married?" while we were watching a movie. Today, we were talking about a mutual friend and I told him that my friend's hoe phase (sleeping w/bunch of people phase) has ended. And he told me that he wished mine would've ended as well. Shoudl I take these as hints or are they random?
