Tom Riddle as you know Voldemort wanted an heir. He was asexual and didn’t want love but he NEEDED an heir. He chose his loyal deatheater Bellatrix.

Bellatrix had just given birth to you, his little heir. He could care less about her now, he just needed you.

“Stop whining, you pathetic woman”

He held you carefully
