Confused

This guy and I used to date a few years ago, never exclusive. But we treated it like a relationship. We broke things off. And recently, we reconnected. We still mess around and give each other oral, but he doesn’t want to have sex again because it involves “deep feelings.” I’m confused because he brings me around his friends a lot now and he never did introduce me before. So I figured he wanted something serious, but I guess not if he doesn’t want sex?? And “deep feelings..” really. Idk what to believe because he still takes me on dates and everything. Not sure what he wants.
