My mom died six years ago. My dad remarried another woman 4 years ago. When she moved in she took down all the pictures of my real mom in the house. It ticked me off so me and my sister put them back up and she replaced them with pictures of her daughter. She is always grounding for stupid little things. I can't take it anymore. She is RUINING my life. I need to know how to handle this. Please give me some good advice..
