So my roommate is threatening to move out, and I don't know whether or not it would be for the best. I do more things around her that I regret. I threaten suicide and scream and throw temper tantrums (its not just my behavior, I am way more negative and upset around her too), and then I hate myself for doing all of that. I had a friend like this once before, and I felt so much better once she left (this seems to be a common thing when I have super close girl friends). So should I let her go and assume that its a mutual thing and an unhealthy relationship. Or should I chalk up all the responsibility and culpability to myself and just try to change myself and preserve the friendship at the same time?
