So, I'm 17 years old and my fiancé, my daughter and I live with my grandma to help her out. We've lived here for a little over a year to help her when my grandpa was alive and dealing with his cancer. He recently died this month, however; we still would like to stay here, and she wants us to as well so the house isn't so lonely for her. Keep in mind, her house is 4,000 sq ft and 5 beds, 6 baths, and she refuses to leave this house, so she would be veryyy lonely if the 3 of us weren't here. My mom used to live with us though, until my grandpa kicked her out because my fiancé, uncle and aunt and I sat down and talked to them. My mom is so immature and my grandma cannot see past it! I have no relationship with her whatsoever, never have. When my mom was living with my grandma, when they'd be away a state away for my grandpa's week long doctor appointments, she'd throw ragers, break things, like chairs because of how drunk her & her friends would get and smoke weed just in the dining room in front of her 9 year old daughter..not only was it that but it was a "gravity bong" my mom made. Prior to living with my grandparents this time around, my mom got so drunk that she had hit and choked me, so I temporarily stayed with my grandparents, even though I told them I didn't want to go back to my moms, they kind of made me & told me not to press charges. On top of all of this, the last year of my grandpa's life, when she was living at my grandparents with us, she had NO job, and was no help around the house and NO ONE said anything. She'd sit upstairs in her bedroom and smoke weed and watch TV all day. Her excuse for not working was because "she had to help with her dad". If something I've brought up hasn't made you mad, then this will. My mom's ex husband, and my sister's dad (we're half sisters) molested me when I was 12 for a little over a year and ever since I told on him and got him in prison for 4 years, it seems like my mom has resented me. Well, come to find out, my mom had been sharing pictures of my toddler daughter with him, Facetiming him with my daughter and having a relationship with him, saying they love each other and sending each other explicit pictures. I was completely unaware of this until my sister mentioned it to me. Honestly, I didn't really believe her because sometimes kids make things up, so when she got completely wasted on St Patrick's day this year, she accidentally left her phone in the car, perfect, and yes, I got on it, which may have been wrong of me, and my sister was telling the truth! What kind of mother tells the man who molested their daughter that she loves him? And wants to be with him? She betrayed me and not only that, exposed my little girl to someone who gets off to that! So my grandparents "kicked her out" that day. I sent her a long message about how I felt a few months later but she never responded. I have no desire to fix this with her and I don't want her in my life, but I can't do this because my grandma has her over every single day! And not to be like a stuck up entitled bitch, but my grandma says, "If you don't like it, stay in your room and don't come out with Brooklyn. It's never bothered you before.", but why should I be the one "punished" for this? I've tried explaining this to my grandma multiple times and she always ends up defending my mom and I'm done with it. What do I do? Am I in the wrong? (the pictures below are the texts i sent to her that she hadn't acknowledged, and still hasn't, even though she comes over almost every day.)
