Revenge is a fools weapon?

Anonymous
So I have this engaged coworker with two kids and a third one on its way. I don't like kids and she knows it, however I'm always affectionate with her, and I throw a bunch of compliments at her on a daily basis. Recently she started paying more attention to me, calls my name more often, walks up to me and asks pointless things for the heck of starting a conversation and so on.
Her boyfriend hired my sister last year as a seller for a small store. He made her work for two months and refused to pay a penny. Should've taken him to court but I didn't.
All the compliments, the flirting and the kindness towards his girlfriend is my way to get back at him. He hates me just as much as I hate him and him knowing I have the chance do these kind of things with his girlfriend drives him crazy.
But! As I can tell she started falling for me. I clearly don't want to have to do anything with her and she knows it, but she just keeps giving me that look, and the way she talks to me changed a lot.
Now, my question is: I know it's not nice to tempt her heart, but should I keep going? She knows I don't want anything from her yet she's foolish enough to fall for it.
