 I'm in a house of 4, and one of the two girls, Betty (fake name), has been the following:

Socially not being a comfortable presence in the room

Moments of crying downstairs uncontrollably due to a high level of stress and depression

Certain moments of lashing out at us due to her own personal issues

Not accepting that things may be deteriorating.

My other girl roommate is stating there is a clear sign of gaslighting occurring between the two of them. Betty, who is much older, has asked this girl to not interact with Betty's friends when she is not present, made unbecoming comments of this girl's appearance, and believes that they are supposed to be really great friends while primarily taking up this girl's time for her own needs. Basically overall a shitty friendship relationship with poor ass communication on both parts. Their relationship now stands completely broken with Betty thinking she can fix it and the other girl not wanting to live with her, and considering moving out herself.

My other guy roommate has this genuine feeling of unease around her. He has stated "I am not comfortable sometimes coming in the front door of my own house". This is the nicest guy around and the person who brought Betty into the mix. He has expressed that this is not a good fit.

With both of my other roommates expressing it's not a good fit (put lightly), along with me for the most part not seeing eye to eye with this woman, I felt that it was important that I communicate to her that I didn't think this 6 month old housing situation was any longer a good fit. I asked her to consider finding new housing, but expressly stated she doesn't have to as that is her right, we are all on the lease. I offered to help her find a new place and do whatever I could do to smooth the transition. I figure it's good to get it in the open.

She said no. My other guy roommate has on his own asked the same of her at this point. Regardless of that, she has communicated she feels it isn't fair and that we have bullied her (probably have at this point just by all of us expressing our issue we have with her (separately)) and she wants to stay and fix this. She definitely feels like we are at fault here as well, that we are scapegoating, and that we can't just fix a problem by "kicking someone off the island". I just straight up disagree that this is just that. I genuinely think this isn't worth trying to work on when we are all just getting to know each other.

We all could have definitely communicated better about these issues we have with Betty and done so earlier on, but the fact of the matter is we didn't, and now we're here. So I operated with what I still have. Not defending myself, just explaining that us, the rest of the house, could have done a better job communicating our issues earlier. Thanks!
