The key thing to me here is him being “hell bent” on it. I think it’s fine if somebodies perspective of dating is different than yore’s. He might think that calling it a date makes it a romantic relationship, and he might prefer that to be exclusive. That’s fine, and asking you is fine. But pressuring you, telling you to stop talking to guys, or taking anger out on you, instead of just having a conversation about boundaries is not.
