Please Read!! I need your opinion!

All right. I need to know this, for real--because it's really messing up my life. One word:
Parents.
Like probably many of you, my parents are divorced. Yeah, it stinks (for most of us), and it hurts real bad. Sometimes your parents marry someone else and you fall in love with them and you are so okay with having a second pair of parents. But what about the people who's mothers or fathers marry someone who you completely hate?
Its not like I can say "Hey mom, I, er, hate your husband. Can you get rid of him for me?"
Uh, let's say: heck, no! That will hurt my mom so bad, and like that'll ever happen.
So my step-dad scares me. Really. I avoid him. When he hugs me it hurts, because he hugs me so dang hard. He'll say:"Don't you love me?" and in my mind, no way, but I say it anyway. He yells at me all the time for the littlest things--and he'll call me names like selfish. Lazy a-word. He says I would be nothing without him. He'll yell at my mom about rules and she'll try to defend herself, but she can't stand up for what she really thinks. He says im a irresponsible person who thinks of only herself. I know you don't know me, but I'm pretty sure I'm not like that. If I disagree on one thing he says--he'll raise his voice, get in my face, and yell and yell until I can't take it anymore.
I feel like I'm falling apart. He wants me to be something I can't be. He wants me to love him--I can't. Every "talk" I have I end up crying--something I hate to do.
I don't know what to do--what to say. If I stand up to him who knows what will happen? What if he gets so mad he slaps me or something? It seemed like he would in times.
All I know is that last night I cried myself to sleep.
