Basically the long and short of it was: my future roommate did something regrettably stupid and I didn't stop her, so now that she has to live with the consequences of her own actions, it suddenly became my fault for not saving her from herself as if her actions were my responsibility.
This, my friends, is why I'm glad I'm gay, because I have only met one or two women my age who are not Drama Machines. The irony is: this is almost a complete Dejavu of my situation with my attempted ex that I dated while I was in denial, only this time, the girl's not dating me.
Life can sure be funny sometimes, especially when you let yourself show completely to people and yet they still get the wrong idea about you. I'm a survivalist by nature, and as such, I live my life by a "we break it, we buy it" way of thinking because naturally what you do carries consequences no matter how big or small they are. My survivalist nature is why I'm the type of person to say "Do whatever you want, regardless of whether or not I agree with it. Just don't expect me to follow you in it", because my actions and choices are my responsibility and others' actions and choices are theirs, so I do not let myself be burdened by the choices of others. Hence, when someone chooses to get drunk while leading on an acquaintance and his ex-girlfriend to have an orgy, I'm going to let them make that stupid choice because oftentimes, in life, the only way we learn is by sticking our hand in the fire. If that's what that person wants, I'll let them have it, even if it creates weight for them to carry forever.
I know that way of thinking makes me seem like a cold-hearted and disregarding person, but the reason I feel no remorse in that is because there were many times in my life where no one was there to stop me from being stupid and fucking up various aspects of my life, and I learned many valuable lessons from it.
