Interesting ethical dilemma - What would Vera have done if
She had a kid with Nico in the new timeline? Vera would have no memory of giving birth this kid. She wants to change things back to where Gloria exists, but that would mean wiping this other kid out of existence. Also, this kid would know and love Vera, while Vera would feel nothing for her.
What does she do then? Accept that her actions inadvertently erased Gloria, and stay back in the new timeline to raise this other kid? Or does she deliberately erase the new timeline and this kid, just to bring Gloria back?
