Parents/Boyfriend Issues

Okay so me and my boyfriend are both 16 and My parents don't give us too many rules because they trust me and know they have raised me to know right from wrong and all of that, but the one rule that they strongly enforce is that if my boyfriends parents aren't home I can't go to his house. I'm completely cool with that, but my boyfriend is starting to get fed up with it. We started arguing about that one rule last night and he thinks my parents are too overbearing. Now he is ignoring my messages and wouldn't meet me for lunch today to talk about any of this. I don't know what to do.. Any advice would be appreciated🙏🏻🙏🏻
