I don't agree with the people hating on the romance, right now the only reason she's rejecting him is because she thinks her future is gonna happen with some random man and not him. She's clearly very attracted to him. And it's not out of nowhere either.
But I'm also kinda irritated with the progression in that area when it's so clearly stalling the paternity test development. If the reveal doesn't happen soon I'm also gonna start hating on the romance plot
