Change is good?

You know those songs that, if you really listen to the lyrics, will make you cry? Well this is one of them for me. I was on Facebook, yes I know not the most trustworthy of news sites, and I saw that my ex-boyfriend’s sister posted that he got in a car accident. Totally smashed the front of the car and the airbag went off. I started panicking in class, I think my professor knew something was wrong because he stopped directing questions towards me.
Why do I still have so much fear for the safety of someone who has no fear for me?
I went and looked at his Facebook page (we aren’t friends on Facebook) to see if maybe I could view anything generally on his page about the crash, and I saw that he was in a relationship.
Dang it. This should not make me feel bad, yet it does. I just hope that this new person is enough for him and that he won’t try to change them like he tried to change me.
