The story of moving in with my younger relative

and living with her isn't what I thought

She smokes in the house and allow her guests to drink and smoke even though most of her guests are usually underage

She plays loud music to 9:00 to the morning and she's always ordering out and leaving a big mess on top of that she tells my mom everything I do even the little things this is why I just can't do it anymore

I just wish she would just tell me if she has any problems with me instead going behind my back

I can't keep living like this and it's only been a week since I've moved in and I'm already ready to just move out she claims I can stay as long as I want but she's forever always changing her mind cause every time I bring my problems I have with her and her guest up she's always talking about kicking me out 

and plus the apartment is always trashy

I'm I the asshole for not telling her about my unemployment check I'll be getting soon I'll have to repay her some way just not now and plus she's already said I don't have to pay her anything I guess I don't wanna feel like I owe her anything
