I currently live with my mom but I am saving up to move out once I’m finish with school. My mom bf who she didn’t know for that long moved in to live with her and then they later got married. Turns out he didn’t have his papers so my mom helped him get his papers, quickly after getting his papers my mom also helped him file for his 3 kids back home. 1 male and 2 female. At the time it was me, my sister, my step dad and mom living in a 2 bedroom apartment. My step dad didn’t really do anything for me and my sister or even get to know much about us. As soon as he comes from work he would go straight to my mom room. He would contribute to the rent but every now and then everything was mostly on my mom. Fast forward my sister left for the navy and now it was just me, my step dad and mom living together after a while my step brother got word that his papers came through and moved in with us. He also later moved to the Navy and a few months after my step sisters got word that their papers came through and they both moved in with us. I notice that my step father would go over and beyond for his kids like teaching them how to driver etc but when it comes to me or my sister we had to beg him to teach us etc. Now that his daughters are now here he always rush to come him from work, always wanna sit in the living room and talk to them etc but that was never the case for me and my sister. He would also help to contribute to buy food for his daughters and everything they need but barely do any of that for me and my sister. Also I just want to say that my mom try to give all of us the same treatment biological or not. Lately I’ve been feeling left out though the family dynamic changed. It feels like I’m on the outside looking in at my mom, step dad and step sisters living a happy life while I’m just there. My step sisters also seem to be taking over my family, the way they both constantly go into my mom room laughing and giggling, saying I love you, mommy this and that and it also feel like the relationship between me and my mom is dying. They also consistently call my grandmother and go over to her place acting like she’s their grandmother it’s very weird. I don’t even do that to their family. I spoke to my mom about this and she basically told me that I’m sensitive and she can’t please me and if I don’t like it I should move out.
