Boyfriend is becoming overwhelmed and distant

Me and my boyfriend have been together for about 8 months now, we have always been inseparable since we’ve met and he is my best friend truly. Recently he’s had a lot on his plate with family problems and moving out of state for work in November. Our plan is to have him move me out to him when he got a place set up out there that is stable and safe for me. So we were planning on doing long distance until then. But his family reached out to him yesterday explaining that they are struggling physically and financially. So he moved out of my place immediately to go move back in with his mom and help take care of her. I’m struggling mentally with all of this happening all in one day and I’m not sure what to do. He called me telling me we can talk about any concerns or questions I have in person this weekend and told me he has strong love for me and he wants me in his life no matter what but right now his family is his number one priority right now. And I completely understand and I’m not mad at him one bit. I’m just not sure how to talk to him about my “concerns” in person when I see him. I don’t want him to think I want to be his #1 priority but I really don’t want him to shut me out and I want to support him. I still want to do long distance, I just need to make sure he still wants this or not because of how much he has on his plate. I’ll always want to be in his life and be the woman he loves and cares for. I just don’t know how to voice that to him without him thinking I want more attention than his family. I just want to help. Please help me find the right words to explain this to him.
