So currently, it is 1220am and my drug headed whore of a sister in law dropped her daughter off to go party. I have to work at 5:30 and now my kid is up and my husband and I are fighting. Wonderful right ?? So a little back story, she and I were pregnant at the same time and she had her kid 2 months before me so you know of course her kids the favorite, she’s the first born granddaughter. Everyone gives into my husbands sister, that’s why she is the way she is and I’m honestly sick of it. His grandpa, who is 73 btw, lives with us and that’s who gives into her and keeps her kid, and I literally feel like I have no say in my own house. I’m ready to leave, like I just want to pack my shit and just go, but I’m pregnant, have no where to even think about going and I don’t make enough at my job to even afford to leave. I’m so over this and everyone giving into her and not thinking my family or the fact that we’re sleeping and I have to get up super early and I’m tired of being the bad guy when I get mad or the person who doesn’t care about anyone but myself according to my husband who ALWAYS defends them no matter what. Idk what to even do, she literally drops her kid off to anyone just so she can spread her legs for more drugs and it’s causing so many fights between us and honestly she doesn’t deserve her kid and isn’t what I can even do about it 😡😡😡
