You are right. In all fairness though if people send her messages that aren't something like "oh my gosh Carrie, you are so brave for being able to dump someone. We love you" she basically being so nice to her she will block them.The problem that Carrie faced now is that she has been saying that Joel is her soulmate and that it feels so different this time. She is so in love. So now she can't break up with him because everyone will flood to her saying but you said this and you said that.
So now she is stuck with him and we all know that creepy man baby Joel won't dump her.
She now she has dug herself into a hole and is in way to deep to get out again
She just blocks people who question her or say something that she doesn't want to hear.
Although I doubt she will break up with him now because of what you have just said
