Why is my dad doing this?

My home life

My names Georgia I'm an only child to my amazing dad Dean Wicks well I thought I was an only child anyway back to the point. I live in Albert Square, it's weird moving in to a new place and not knowing anyone but I've settled in just fine. A couple of weeks after we moved in I met my Uncle Mick Carter and his wife Linda Carter and their children Nancy Carter and Lee
Carter they also have another son called Jonny but I'm sure where he is. I sat there like an idiot messing around on my iPhone when Lee walked over,

"Hey Georgia what's up you've been wired since you got here," questioned Lee with a smirk on his face.

"Erm nothing just like my alone time I guess," I smiled back.

"You sure if you need to talk I'm here,"
I looked up and hugged him,
"Thank you Lee it means a lot"
I got up from the bar and walked up stairs where I over heard Linda talking to Dean.
" Dean leave me alone , I'm happy and I don't like you back sorry," Linda sobbed
"You will do what I say and of course you like me don't lie to me Linda ," Dean screamed
"I don't Dean I never have and never will"
Linda ran out of the door and I hid so she didn't see me. I wonder what that was about I lay in bed that wondering what my dad was doing to Linda I wanted to ask but I couldn't.
My had been in prison when I wasn't born something to do with me I think he never fully told me the truth only that my mum don't want me it annoyed me that I never knew my mum and that she didn't want me if I ever met her I would ask her these questions.
