Call me crazy but I got a theory

The reason Harry Potter wasn't living with the Weasleys after the gontlet of fire when Voldemort found a way around the protection charm is that Dumbledore didn't want Ginny Weasley getting pregnant making Harry Potter question if he should let the dark Lord kill him or not because Harry Potter wouldn't want his child to grow up without him parents like he did

It's either that or Dumbledore really was a crazy old man whose only intelligent play was having snape kill him to trick the dark Lord

And before anyone here dare try to argue my point

Ginny Weasley has had a crush on Harry since at least book 2 and was described as all boys want her and she is confident and fearless in the books

Harry was a stressed out teenager who was always shy and had low self esteem in the books
