Roommate

So I’ve been living with my roommate and shes had a couple jobs since we have lived together and I just found out she got fired from her job that she currently has, it was a great job too. Apparently it was a mass lay off but I really dont know if i believe it at this point because she lies all the time and she has been let go from previous jobs. Im not sure what to do because she wont be able to pay rent or her bills and its gonna be super tight with money
