An Open Relationship Advice

I had made a post about this before but I realized that I was not as detailed as I wanted to be in order to receive the proper advice so I wanted to redo this post and see if the advice I received before is still the same this time.So let me start by giving you guys a bit of a background about me and my boyfriend.I am 22 years old,I am from New York,I am a caregiver for my mom and I am also a paid streaming host.I also do not have any children.My boyfriend is 27 years old,he is from Chicago,he has 5 occupations,and he is also a paid streaming host.He also does not have any children,but he was formerly engaged back in 2022.Our birthdays are a few days apart,we share similar disabilities,and we started dating October 4th.We are currently in an open long distance relationship and this is my first open relationship.He did briefly explain things to me and there is another female involved in the relationship but he is more active with me and we claim each other more than the other female does.In other words people who know us know only about me.But he isn’t really public about his relationship on social media.My current situation is just me being still unaware of certain things,andI have been wanting to ask him more questions but due to his schedule being so hectic when we do have the chance to talk on FaceTime that is the last thing that we think about talking about.How do I respectfully approach him with this conversation again?

PS}I hope I gave enough details this time to help with giving advice.
