By skyforbes I (M18) practically always had an issue with "Sadie" (F17) who I've known since kindergarten. Her brother (20M) bullied me for 6 months when I was in first grade. Him and his friends bullied me and a few others but I was his favorite target. My mom got involved and he got in a lot of trouble especially when he was bullying younger kids. After her brother got in trouble Sadie turned on me and she has been persistent. My mom was in and out of each school I went to making sure I was in different classes than Sadie and that the school didn't let Sadie get away with bullying me too. She didn't stop. At least she didn't stop until we found out my dad is her bio father, which was 10 or 11 months ago.
Which brings me onto finding out my dad cheated on my mom (and my parents are almost at the end of their divorce now, dad has tried so hard to stop it) when she was pregnant with me. Sadie's mom wasn't married but she was with Sadie's brother's dad and they got married when Sadie was 2. Sadie thought he was her dad too. But he didn't treat her the same and I have been told over and over to be forgiving and compassionate because the exclusion and verbal abuse she got from her "dad" made her lash out. I was pissed when I found out. I was pissed at dad for doing that to mom. But of all people Sadie he had to make? Yeah, I made it clear to everyone that Sadie might have the same bio dad as me but I would never be her brother and I still hate her so she can fuck off and leave me alone.
My dad's family aren't talking to him either. They don't like the mess he made and they tried to rally around me and mom. But a few months ago they started to change and would ask us to change our feelings toward Sadie and to find compassion. My mom had none for her and she told dad's family members there was no way she would family up (her way to describe it) to a girl who tormented me for a decade and even cyber harassed me with messages telling me to KMS.
I told dad's family that I wasn't willing to have a relationship with Sadie. I said I wouldn't stop them but they shouldn't expect to see me where Sadie will be. They told me a million times she's my sister and I told them she's dad's affair kid and a stalker and I hate her. I said dad fucking up and making her doesn't change that.
Sadie's first family function is going to be Christmas and dad's side are so annoyed I won't show my face for even a little while. They told me it would be good for me and for Sadie and I told them I don't care what's good for Sadie. I said seeing her would ruin my Christmas. Just like having to pretend I don't hate her would ruin it. They told me I should see all she's been through and be willing to at least see her for their sakes.
AITAH?
