My question involves landlord-tenant law in the State of: Alabama

Living in an off campus housing apartment for over a year. had other roommates and got along with well. The landlord choose three other new roommates and moved them in with not even knowing their names or given any notice of their arrival and being surprised as one moved in after 8:00pm. The one that moved in at 8:00pm started threatening me and moving around my stuff. Myself and one of the other roommates were woken up at 3:30 in the morning by the same girl and her boyfriend coming back to the apartment. Myself and the other roommate came out of our rooms and the boyfriend then threatened me and the other roommate.
My question is due to these circumstances do we have grounds to break the lease? I have anxiety and this is making it worse. I feel unsafe and no longer wants to stay there. We tried talking with the property manager and was told that we would have to work out the roommate issues.
