how do edward actions both hakikisha and refute what bella read about Wanyonya damu

Edward always acts wierd around Bella, so she begins researching everything to find out what's going on and why he won't tell her.

Well obviously Edward wouldn't want her to find out because she might have freaked out au something silly like that. But Bella is perceptive so she realises he's something other than human so therefore starts researching what he can do like; super speed, strength, he's ice cold & he never eats.
Eventually he has to tell her what he is because she's already found out so much through researching him.
