Closing her ears

Hi mummas.. someone please help me 😔😔I’m just so broken when my LG tells me that I don’t love her. My little one is not at all listening n going through lot of emotions and lot of tantrums. I’m just crying every single day. If I tell her 5-8 times she doesn’t listen but if I do in a playful way she takes it in a funny way n ignores what I tell her. I do have a little baby girl who is 7months old where I need to look after both of them when her dad is not at home. Whenever I tell her a In a strong way saying please don’t do that - she’s screaming very loudly and closing her ears, throwing all the toys, she kicks me with her feet, punches me and pulls her baby sister hair too. I just don’t know where I’m going wrong. Sometimes if I say her in a sweet way she still ignores me and bangs all the rooms door, goes straight into her room saying that I don’t love her at all.. I buy her every single thing that she asks me and I spend most of the time with her than the baby. I do sleep only with her because I leave my little baby with her dad in the night to be looked after her. Every time when I tell her where she is doing wrong, she immediately closes her ears with hands and says that too noisy and too loud, just ignores, leaves the room or bangs the doors/throws/shouts/cries very badly.. even if my husband corrects her she does the same thing, so my husband blames me that I don’t even let him correct her. All she does is crying, screaming and throws everything while he talks to her. I’m just scared what my neighbours think everytime my LG screams so loud. We live in a semi detached house. Please help me where am I’m going wrong.. she goes to nursery 2 or 3 days a week full time. Thank u so much in advance xx
