let me just say... for once!

It is hard for me to explain the problem I, and the rest of my roommates are having with our other roommate. Let me just start from the beginning...
There was this girl down the way who had her boyfriend spend the night at her apartment from Thursday to Tuesday. Her roommate, did not feel comfortable with him there. She went home over the weekend and came back and he was still there. She couldn't tell her roommate so she spent the next few nights at our house. One of my roommates and I felt really bad and could see what kind of a position this roommate had put this other roommate in so in order to find more information we went to our RA anonymously to find out what would happen to the roommate that was too uncomfortable to go home. We didn't give any names... it was all hypothetical. Our RA said that she could get in trouble just for knowing what was going on... we encouraged her to talk to her roommate about having him leave... but, she didn't want to start conflict... so we just left it.
A week or so later, it comes up again. This time, the girls are confronted by our RD (resident director) because she saw a guy walk up into the apartment after hours and when she sent an RA to go check on it, that apartment was the only one that didn't answer their door, even though their lights were on. The RD knew there was something fishy. She called for a meeting with the RAs. This story came up, and when our RA heard this, she had to finally speak up and say I had some girls come down to my apartment in the middle of the night asking what would happen. It was obvious then that that was who we were talking about, though at this point we had not said a word about who it was.
Our RA pulled Victoria aside the next day and said, listen I need to know their names. I need to know that we are talking about the same people. Everyone that knows and lies (whether by omition or otherwise) will get in trouble... So basically, she had to tell them.
Now, the girls who this all happened to... the apartment down the way... they flat out lied to the RD for weeks now (barely coming forth yesterday)... It got down to the point where the case had to go above our RD to her boss and her bosses boss. These girls were going to get in a lot of trouble... possible kicked out because they couldn't tell the truth. Not only that... what has really made my life a mess was that they expected everyone to lie for them and they came over here before I had even said anything accusing me of "tattling".
The girls completely forgot that it was their problem. They shouldn't have let a guy spend the night. What did they think was going to happen? I didn't even tell on them to begin with... atleast not until they were already caught by the RD of all people.
So, anyway... Monday, the RD came to three of us and said, "listen, I need you guys to come forward and write me an email explaining the details, because this girl is flat out lying to my face." Three of my four roommate had to make that descion that we wouldn't lie. And, the other one sided with them, though she would never admit it.
Here is where I am having problems. This fourth roommate has completely abandoned our apartment and our friendship... though, again, she would never admit it. She pretends that everything is ok but at the same time avoids conversations, dinners, saying simple hello or goodbyes... all of which she was well known for. I feel like she has abandoned our friendship for something that is so stupid and petty. I know that these people were her friends... but, you need to grow a backbone and some integrity one of these days.
If the RD says you are going to get in trouble for a choice that someone made... a selfish person who didn't care that it would effect everyone around her... and continued to lie about it for weeks now... why would you pick her? She's not going after your best interest... she just made you out to be a liar. She just made you out to be shady and undependable.
Overall, I'm just sick of all this avoidance. If you have a problem, lets talk about it like adults. If you are bitter with me, tell me why. I'm not even asking for you to forgive me but, atleast for the chance for an explanation. I don't that is too much to ask for, and I think that our friendship meant more than what it is being treated like now.
There isn't any more that I can say, other than that our whole house is feeling this strife. We are supposed to be sisters. If someone is growing or falling or having a hard time... we are to help each other, be there for each other... and so far that is working with my roommates... but, not this one. And, that alone, breaks my heart the most!

I'm sorry that this has been such a long blog. No one really reads this... but, I really need to just vent. I've had this bottled up in my heart for too long.
If it requires me to let go... then I will, but I really don't want to let go of a relationship that I have... one that I treasure so much... and a woman that I am so inspired by. I'm inspired by all of my roommates. They are amazing woman. We have a profound effect on each other. God truly gave us this year and has answered my prayers!
I'm done!
