I'm so done with my bfs sister and her kids treating as if I'm nothing or sitting there talking trash about me and my child I'm seriously done and then we get here and he leaves me by myself when we get here so I'm even more uncomfortable. seriously ur going to sit there and whisper saying is she pregnant I couldn't tell if she was or just fat. I'm just about done
