Roommate is trying to make me pay pge bill even if I’m not living there

So for context I used to live with female 23, and female 20, us 3 girls lived in an apartment together and for personal reasons I moved out I am still on the lease and paying rent but one roommate is trying to make me pay for some of the pge bill even tho I have not been there for those dates and my name isn’t on the pge account. So can she take me to court over that?
