I mean I don't know how she reacted but I feel that since she thought that she already had enough kids and Paul D wanted to her two have his kids she probably regretted it afterwards, also since Beloved was crying downstairs.
And since beloved was crying downstairs in the book she probably felt regret and remorse afterwards, Paul D on the other hand probably didn't care, and he probably felt happy because in the book it said he had a low-ego or like low self-esteem so the fact that she agreed orobably made him feel good and happier about himself.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)
