<human>: Can you provide a brief rundown of the text in within 3 sentences?

Last night I admitted to my mom that I wish she had have left my dad when my older sister was a baby. My dad had been cheating on her with her best friend and threatened to take my sister away while he was trying to convince my mom she was crazy. She stood up for herself and he choked her and then spent the night in jail for it. She took him back on the condition that he stop cheating. Three years later I was their "commitment child" and two years after that they had my brother. My dad continued his double life and trying to make my mom feel like she was crazy. They wound up splitting up when I was 7 because "since all of the kids were in school" we didn't need him anymore.
<bot>: My family went through hell and back because of my dad and I wish that my mom left him before I was born even though it means I wouldn't be alive.
