You may have missed an integral part of this movie. The whole kidnapping and captivity of the protagonist lol.

I do not believe that he kidnapped her.
It happened the way he said it did.
He was driving too fast and ran her off the road. He could have left her there but he chose to go back and save her life. The ungrateful POS didn't show any aprkation.
Howard was nuts but that does not change the fact he saved her life. She should have kept her mouth shut and not cause any problem until it was safe to go out.
The most important thing is sincerity. If you can fake that you've got it made.
I want to win the Nobel Peace Prize so bad that I would kill for it
If boxing is a manly sport why do they fight for a purse?

Howard was insane and kidnapped her. What are you talking about?
