Why guys always pull away from me after the second date?

They’re obsessed with me before we met or after the first date, but they started to pull back after the second date.
They still talk to me but a lot less. It happened to me many times. They don’t try or ask me out anymore.
FYI i didn’t say or do anything weird. I acted exactly the same as my first date….
