<human>: Can you condense the text into a few key points?

Because of personal differences, my roommate decided that she no longer wanted me to live with her even though we are both on the same rental agreement and the agreement is not over for another 7 months.  I agreed to move out and she told me she would "take care" of the next months rent, what ever that is supposed to mean I didn't know. 

She gave me deadlines to get out of the apartment (that I followed) but refuses to sign a document allowing me to terminate my portion of the lease.  So technically, my name is still on the lease and it is just as much my apartment as it is hers, so I took it to liberty to show people my room to try to get someone to move in for me, as the land lord said I could do, as I have brought to his attention of the problems my roommate had been causing.  

Today, while I was showing someone the apartment, my old roommate (who still lives there) came home and stormed into my room and started yelling at me, stating that I had no right to show the apartment to anyone and that I had to get out, scaring the potential new resident of the apartment. 

 She has demanded that I give her my house key multiple times before this and has threatened to take me to court if I don't continue to pay rent after she has kicked me out, made personal threats, and attacked my relationships of family and friends.  She has never once contacted our land lord of any issues and is doing all of this without the land lords knowledge. 

Is there any legal action that I can take? I have recently moved in with a boyfriend until I can find a place of my own and am helping pay my boyfriends rent for the time being. I do not want to pay for Aprils rent at 2 different leases that are both due by the 5th of April.  

Thank you and I appreciate any help.
