You have a father that's a alcoholic, and is very abusive ever since his wife left/your mom. Leaving it just you and him (your his daughter) so he started drinking strong alcoholic beverages and abused you, and flirted with you. He'd sometimes hurt you badly but then start sobbing randomly.

And yes, he did flirt with you at times because he thought how you looked just like your mother. And he'd peek when you would change. Which was..weird One day you were supposed to get picked up by mark but didn't. So you walked home in the rain.
