I used to be so bad about this when I was younger. Being an introvert makes it much easier to deal with things inside myself. Being intuitive makes you think that it's OK to shut someone out because lots of other possibilities will open up elsewhere. Being a feeler makes you not want to alienate other people by putting things out in the open that might make you both uncomfortable. And being a judger makes you act much more quickly and with more finality than you really should have -- and then you realize it's too late. And then you end up feeling even worse! I'm not saying any of this to justify your friend's behavior, because it is immature behavior, but hopefully you'll understand that it's not really a slap in the face to you, but more of a "this got out of control and this is the best way I know of to handle it" message on her part.
