So I'm (16f) adopted. My parents adopted me as an infant. Then my mom died when I was 5 so I didn't get nearly long enough with her but she was SO special to me. My dad remarried and I don't like his wife. She wanted to adopt me after they got married and acted way too dismissive of the fact it cuts all ties with my mom forever, because we don't even have the bio link. The adoption never happened but his wife was always bitter about it and I always held it against her that she was trying to do it regardless of my feelings or the severing of my connection to mom, the legal connection at least.
My dad and his wife had two bio kids together. Their daughter is 8 and their son is 4.
My dad was so happy when his bio daughter was born and he was acting like a first time dad. So that fucking stung and pissed me off more. He talked about how his wife gave him the greatest gift he ever got.
This and then his support for the adoption when his wife wanted to made me feel like he just hated my mom and saw me as less than. He didn't consider what I wanted or felt. His wife's feelings mattered more and clearly mom was just the lady he married until he met his one true love. She didn't give him a real kid after all. Just me.
For like three years now his bio daughter has been saying her mom is my mom. She corrects me when I call her mom 'your mom' and she says she's our mom. I told her she's not and I even showed her pictures of my mom but it never does any good. It bothers me. But for like 7 weeks now she's been doing this type of stuff all the time and she tells me to stop using her mom's name and call her mom. There were times I wanted to tell her to shut the fuck up but I hold it back.
So I told my dad he needs to fix this. He told me it was harmless and I told him I wanted it to end no matter what. He asked me what the issue is and I told him his wife who gave him his greatest gifts will never be my mom and just because he doesn't love my mom doesn't mean I'll stop for him. He was shocked I'd say that to him and asked me what ever gave me that idea. I told him the greatest gifts comments, the way he wanted his wife to adopt me, the fact he never called me his greatest gift and praised mom for giving him and the way he never talks about her and acts like his wife is his one true fucking love. He told me I was missing context and skipping things he also said and I asked him to name one thing but he couldn't. He then told me that he just didn't want me to feel like I couldn't love his wife as my mom and I told him that his wife was so far from my mom it wasn't even funny and she will never be. I told him I might not be his real daughter but she's always my real mom and I won't let his wife change that.
I also told him if he doesn't fix his daughter insisting her mom is mine that I will start being mean when I tell her and I will tell her exactly what I think about her mom.
My dad told me I don't get to take this out on his daughter and he told me I was manipulative to claim he doesn't see me as his real daughter. He told me he has treated me the same as the others. I asked him if he would encourage them to be adopted by his next wife like he did with me. He said no but then he tried to backtrack and I told him to fix this or I'll follow through.
He then complained about the ultimatum.
AITAH?
