"Congratulations, Ralph, you finally cut her out of your life. I hope you're happy."
That sentence can be misunderstood, depending on the tone. There could be a bit of disdain there with "I hope you're happy." There could however be sincere happiness for the other person with "I hope you're happy"
The problem is that it's best to cut people out of your life if they're toxic, as common and basic as that sounds. With friends who make you feel terrible no matter what you do or what they say, it'll all come crashing down no matter how many empty, meaningless words are exchanged. So it's best to just cut it.
The thing I'm worried about is getting the call or message from one of her family members, saying she's in the hospital or worse. At the same time, maybe it's for the best that I don't give a damn.
No matter what, I'm not supposed to care.
