So... Am I dead inside?

My sister just called at about 12:00 tonight to tell me that she is divorcing her second husband due to his emotional abusivness, and I can't say that I really cared. I mean I don't know if I don't care, or I am tired, or if I don't love my sister anymore. I just didn't really care. Of course it seemed like she didn't either, but I think that I should care. Of course this time it wasn't my fault in any way. The first time I felt a little like it had something to do with me, but this time I wasn't even there for the wedding. Of course I didn't really like him. College sure disconects me from my family.
