This isnt the usual kind of post on here, but its to do with character and I would love some advice from you lot (since I'm learning RP)

My grandma causes alot of issues at our house and causes alot of fights but wont leave to go to her house.

My mum wants to, but wont kick her out, because she's worried about her reputation, so I feel it's my responsibilty to do something.

What do I do? Should I get police involved to help force her out? Or should i suck it up for the rest of the year (going uni next year) and look out for myself more?

Thanks for your inputs.
