People dont respect me.

By people i mainly mean family. Even when i say no constantly they dont care. I buy stuff for my kids i tell them not to touch or eat it and its ate and no one knows who ate it. My Couch that im still paying for is recently broken( btweenvmy brothers and dad they did it when i confronted them about it they all said they didnt know who did what) my dad doesnt pay, he ignores me, doesnt clean, he just.. is here. Everyone has a move out date but it just sucks . I wonder why they dont respect me
