Oh, you’re right, I had mistaken it with this:

In 1998, Knight and Price fought over his refusal to marry her. In retaliation, she videotaped items he had allegedly stolen from work and sent the tape to his boss. Although the items were out of date medical kits that he had scavenged from the company rubbish tip, Price was fired from the job he had held for seventeen years. That same day, he kicked her out and she returned to her own home while news of what she had done spread throughout the town. A few months later, Price restarted the relationship, although he now refused to allow her to move in with him. The fighting became even more frequent, and most of his friends would no longer have anything to do with him while they remained together.

Why on earth would he get back together with her?

I mean, I probably know the answer. He was lonely, and unstable people can be remarkably good at seducing lonely people. Like they can smell their victims. Still though.

Edit: Oh hang on, no, this part is AFTER she stabbed him in the chest, after he told his coworkers he thought she might murder him:

She later arrived at Price's house while he was sleeping and sat watching television for a few minutes before having a shower. She then woke Price and they had sex, after which he fell asleep.
