if this was a good relationship and you think this isn't like her, try to talk this out. She might just be a little blinded with joy/pride/ whatever and not realize how she's coming across.
If this becomes the "new her" or if this was her all along and you're just seeing it for the first time, then quit and move on.
Best advice so far.
I know how difficult it is to handle such personalities, but trust me that everyone makes mistakes.
Sure, being condescending is a very rude thing, but it just a mistake, like everything else. A person who is condescending shouldn't be labeled forever, because it can be just a passing thing and as
@lazymed pointed out, it can be just an accumulation of post-traumatic stress and narrow-mindedness.
You know I have a very good friend who gets incredibly rude when she is in high-pressure situations. She made things for which others would have probably left her and label her as "b*tchy", "egotistical" and "evil", but I decided to not do this. Instead, I always wait for the clouds to pass so that she can clear her mind. When she does this, suddenly she becomes the lovely person that I first met.
Sometimes when I said her in a fun way that "You're really bad sometimes, you know that ?", she replied to me "I guess, life has made me that way."
While I agree it's not a justification and we all must own who we become, I genuinely believe that every person should be analyzed
only by taking into consideration his/her own life, because only then you can truly understand why he/she has become like that.
Sure, not many people stop to think about things like that, but don't ever expect to understand someone if you aren't willing to dive deep.
People are not made up by a static psychological profile , but a dynamic one : everything they experience shapes them in a certain way.
When a person behaves in a certain way, I always think about :
" What type of life did this person have ? "
" What experiences shaped her thinking and in what way ? "
" How was she educated ? What paradigms did her parents teach her ? "
" What is the core of her being ? What are her inner fears and wishes ? "
" How introspective is she ? Does she even realize what she is doing ? "
Sure, it's way easier to just say "Hey, just dump her, bro"
But who said that dealing with people was supposed to be easy ?
Enjoy the challenge !
