He became unresponsive and distant after I revealed the identity of my grandfather?

When we first met. I didn't tell him who my grandparents are. He didn't ask me and that didn't come up until recently. They are the kind of people you can look up on the internet , on YouTube and on google. An old family with a history in politics and the military. Loved and respected a lot by some people and hated by others. This is the reason why i avoid telling people my full name because i want them to know me as a person and like me for me. Not for my family or my connections. To make long story short, he was very responsive and interested up until the moment i told him my full name.. he took it in a stride but later on grew distant. And not as eager to be with me as before. What do i do? Should i just pull away? He hasn't responded to my recent texts and it's been more than 24 hours since i sent them.
