Last Summer, my moms boyfriend moved in. They'd only been dating like 2 months. No one in my family has ever liked him. He's selfish and rude and well just really inconsiderate of women. My mom seems to ignore all of his flaws. Anyways, last summer, my mom and i got in a tiff about how i'd been acting. It wasn't a big deal, but we were arguing when her boyfriend broke through a locked door and started screaming uncontrollably in my face and had me cornered against a desk. I was scared and didnt know what to do, I kept trying to get away but he would push me back, so i eventually ended up trying to punch him to get away. I was 17, and 92 lbs. He then picked me up by my shirt and waist and threw me across the room against a wall.
My dad made me file a police report, but due to CA state law, and lack of evidence, nothing happened with it.
To lead on, my mom had promised me he was leaving and never coming back. I left home for 2 weeks to get away, came back and he was still living with us. Now they're scheduled to get married next April, but no one in my family supports it and she doesn't notice. We've all tried telling her but she doesn't care.
She pushed away her best friends of 18 years because of him, and she doesn't know that on her fathers death bed, he told me he couldn't stand to see them together and how much he was sorry for me because he hated her boyfriend. No one likes him, not her 6 kids, or her mom and 2 sisters. But non of them have the heart to tell her because they don't want to hurt her.
What can i do? I feel so betrayed by my mom for staying with him and now getting married, and i cant even fathum forgiving her for letting him back in after last summer. I feel like she doesn't even care what happened, when im permanently scarred and have talked to several counselors about it. .
