A teenage girl on Reddit is frustrated that her stepmom wants to be as close with her as she is with her biological mother.

"My parents divorced when I was a baby. My older brother was 2 at the time and he's now 17. Our dad remarried just over a year after the divorce and they created a blended family. Dad had us, our stepmom had [two] boys who were pretty much the same age as my brother and me and they have three more boys together," she wrote on Reddit.

The girl's parents have split custody, and although she has known her stepmom most of her life, she has never considered her stepmom "equal" to her mom.

"My mom comes first. If I want motherly advice I go to her. It's my mom I want when I'm upset and stuff. My stepmom is fine but she's just not my mom. One thing about my stepmom that really makes me awkward around her is she always wanted to be the mom to a daughter and she has no girls," she continued.

The teen explained her stepmom "latched" onto her from the moment she met her dad and even used to try to dress in matching outfits.

"She has this weird fixation with me. She's not upset that my brother considers her second best but it bothers her that I don't consider my mom. She tells me every year just before Mother's Day that she would love for me to call her on that day while I'm with mom. She will also ask if I want to do some mother/daughter mother's day event with her every year and I always say no. Then I get to see her face fall and she'll start to cry," she detailed.

The teen just doesn't have the same "kind of love" for her stepmom as she does for her mother.

"She makes me so uncomfortable with her obsession with me being a girl for her… I told my stepmom she needs to accept she will never be the mom to a girl and I will always be my mom's daughter and not hers. She told me she has been in my life since I was a literal toddler and should see them both as my mom, when I spend the same amount of time with both," she added.

In response, her stepmom told her "it's disgusting that I would reject her over and over again and then tear her down like that when she could easily be my second mom."

Users backed the teen and told her that her feelings are valid.

"You said your dad and her had [three] more kids together? Kinda feels like if one of them happened to be a girl she would only care about you as much as she cares about your brother," one person wrote.

"You’re just a placeholder for a daughter she would’ve loved to have had. Your dad is making this worse by not intervening," another commented.

"You don't need a second mother. I can't stand people who think you can control your feelings toward them and then demand you do so anyway, whether you want to or not," someone else chimed in.
