Disclaimer: I Do Not Own Harry Potter.
It was easy getting a man who loathed his wife to stray, but getting a man who loved his wife was a challenge.
Bellatrix loved challenges and Arthur Weasley had been her greatest. It wasn't just that he was devoted to his wife, although that had been a major obstacle to overcome, there was also the fact he hated her and everything she believed in.
She hated him and everything he stood for but the pleasure she got knowing that she had the power to make a man who loved someone else want her was enough to put that hate to one-side.
One of the top twenty moments of Bellatrix life had been the moment she got Arthur to the utter the words "I love you,".
And like so many men before him, he had meant it.
