<human>: My mother married my step-dad about 3 years ago and I've known him for a total of about 5 years. 

We have always argued with each other but a little before my HS graduation we began arguing much more and worse than before. We're both stubborn people but I'm open to others opinions and he is not.

I find myself stressing out, crying, unhappy, insecure and at one point wanted to just not exist. My mother just pretends all is well because step dad has a VERY strong personality. It's come down to a point where I want to move in with my boyfriend of 2 years or just be submissive to my step-dads ways.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My step-dad is kind of a dick and I don't know what to do anymore. Move out or just give in to anything he says.
