my mom‘s boyfriend‘s niece is obsessed with me. Am I overreacting?
so my mom has been with her current boyfriend for about three years now. When they first started dating, we all moved in together. He has three kids and a niece. So it’s just me (19) and my mom. My mom has been taking care of the whole entire family since her boyfriend is going through a divorce with his ex. That’s besides the point though. He had one of his other nieces living with us before this one came in and the other one moved out. So this one moved in. Shes 17 and honestly driving me crazy. She claims that she sees me as a sister but honestly, I don’t even know anymore. She’s completely spoiled rotten by my mom‘s boyfriend. Like terribly spoiled. I stay off to the side and do my own thing. She’s always made comments about how she wishes she had clothes like I did or how she wishes she had the confidence that I had had to wear certain clothes or whatever the cases. What you know, whatever. But it just kept on getting worse. She mentioned to my mom today that she doesn’t think that I do anything around the house regarding the kids. the kids aren’t related to me in anyway. They’re not my siblings, cousins or anything. And for the past two summers, I have watched them while everyone was at work. She also likes to play the victim card a lot. We all have gone through our own things in life so honestly comparing trauma and childhood is kind of crazy. She talks to my mom about almost everything and I’m letting her do that. Letting her steal my mom and take time away from me and my mom. She’s made comments towards me about how at least I had my Mom growing up. Which it was just me and my mom never anyone else. She keeps making more and more comments about my room, my hobbies, my clothes, literally anything and everything. She takes everything that I have and complains when she can’t have them. I collect dolls like I’ve had since childhood. She tries to start collecting everything and doing everything that I do when she previously had no interest in it. She’s told me that some of the hobbies I have her stupid but then decided she wanted to start doing them too. I’m trying to figure out if I’m overreacting or if this is just something people do? Especially teenage girls. I just don’t like how she tries to guilt me for feeling and doing certain things. It honestly feels like she’s doing all this on purpose but then makes fun of another friend that I have for doing something similar. It’s honestly just annoying. i dont see why she doesnt think we can be two different people. am i taking it too personal or is this just something most girls do?
