Need to have a roomate removed---Updated question?

When I moved in 3 of us signed the lease. Today one sent notice to the landlord that she is moving out and is removing her name from the lease. In March the second roommate (roommate B) moved in her girlfriend with notice that it was non- negotiable. I recently found out that she never told the landlord that she was doing so. Roommate B is completely insane. While I was away she called the landlord to try to have me evicted. The landlord is not going to get involved in this as it is a personal issue and he refuses to evict anyone on the lease. Roommate B's girlfriend has now the option to add her name to the lease. Roommate B is a complete nightmare. She pay's the rent late that automatically comes out of my bank account on a preselected date as to insure that it is always with the landlord by the 1st of every month. Roommate B refuses to understand that when she pays me the rent late that it means that she is borrowing money from me. After my return from being out of town I was confronted by roommate B that the landlord is going through the process of having me evicted. I spoke with the landlord and found that he has no such intention and wants no involvement in this. The day after roommate B's computer stopped working (according to her) and that there was nail polish on it and since I had done my nails the night before I was the one who did it. In all honestly I believe she did it herself to create a fight between everyone. Last week I gave her an offer of $3000 to leave the apartment by 12/01/09. Today she stated that the offer was pathetic and she was not moving and she was going to make sure that I was. She also stated that she believes and is telling everyone that the reason the landlord is not evicting me is because we are sleeping together. This could not be further from the truth as he is married with 3 young children and I am in a relationship as well. During an argument today she again blamed me for breaking her computer (that I must add is old and has been crashing for over a year) stated she is going to stay in the living room as long as she feels like to make me uncomfortable so I would leave. When I told her that her immature actions are nothing more than annoying she picked up a jar candle and threw in onto the keyboard of my computer. I was able to fix the damage but I cannot continue to live my life this way. I truly love this apartment it has plenty of space (that for the past year and a half I have been the only one to clean the common spaces) I do not want to move I am currently 3 months pregnant and the set up of the apartment is prefect to add a nursery and she has continued to state that she will make my life hell until I leave and destroy my personal property. I really need any and all advice to get this nightmare out of my life. State CT---Latest update: Sunday night before I went to bed My other roommate was sleeping and the bedroom light in the crazy roommate's room was on. As always I locked the door before I went to sleep. I was woken up later to her drunk sreaming from the bottom of the stairs "Lock me out you f-ing ******. I'll kick your *** you F-ing ******" Over and over untill her girlfriend pulled her into her bedroom. I have spoken to a lawyer and that triggered something with her and she was going to call me back but I haven't heard from her yet. She did let me know that in the state of CT since the relationship is platonic that I cannot get a restraining order against he
