Why does my boyfriend act weird on the phone when it comes to other people?

We are long distance. He lives in LA (california) and me in northern california. Well we been talking for 5 years online everyday and constantly. Thing is he is very private, and has hid me online, his family, and friends etc everybody. We just started talking on the phone about a year ago around this time, and the only person I have talked around is his nephew who is 15 years old and barely started to talk around him in August and he doesn't even talk to me or join in our conversations. I always got annoyed by how he treated me and thought he was hiding something else, and have went and told everyone about him online they all thought he had a wife/someone else in his life, but that isn't true at all. We are on the phone pretty much all day long even though he doesn't talk to me I know for sure he is single in person and he lives with his family. He is 37 and i'm 30. He doesn't talk to me at all when he's in the house and his parents are around, his parents are older around 60s dad around 70s/80s, they have answered his phone once but i hung up as soon as that happened. i thought it was weird. whenever they are gone he will talk my ass off though and the only time he ever talks to me is when he is ubering, he even lowers my volume when people are around when he's ubering like picking up an order or dropping it off. i just don't understand why he's so weird when it comes to talking to me or about me to anyone. People say I'm not ugly so i dont get why he treats me like a secret, i also respect him and get quiet when he's around others and he still lowers my volume/hides my video camera so they can't see/hear me. his mom is super loud and always yells but he has it so i hear her all the time even though i told him i didn't like hearing her. she has woken me up out of my sleep a couple times and he doesn't care about that. they are religious and she is always praying. could that be why he acts that way? what do you think is wrong with him?
