Is it okay if I say good riddance to my ex-best friend if I find out she is drinking herself to death?
What? Wait. Why do you not have sympathy instead?
No, I hate her because she assaulted me physically in the past. I don't see why I have to have sympathy for when she makes bad choices.
Sometimes people have to make their own mistakes, even if it's over and over. It may seem callous, but you're not obligated to stick around and get wrapped up in that mess.
Exactly! That is why I feel like I do.
Your frustration is showing for sure. Just try not to be so nasty verbally, it won't help her situation. You can still do the right thing though and guide her to a recovery center.
