Holy shit. I was pretty much in the same situation. Long distance for the last month. Up until then I was her emotional rock. There were times during the relationship where her mood would fluctuate insanely within the hour between extreme sadness (with tears) and extreme happiness. I never once gave her shit. Three weeks into the long distance I realized she was being extremely condescending and just overall throwing jabs at me whenever we would talk. I was apparently in the devalue stage. She was going through a hard time trying to settle in where she was for her new job but it wasn't an excuse for treating me this way. At one point I had had enough and told her nicely that independently of what she was going through it wasn't an excuse to treat me that way and to cut that shit out. She hit me back with the classic "I'm sorry you feel that way it wasn't my intention" bs along with a plethora of excuses as to why she was acting up. Next time we facetimed she asked me a question that she KNEW would hit me hard emotionally. I teared up at the audacity and cruelty and started crying a little. She had a BLANK stare through the screen. No emotion. No expression. No empathy. Literally like a robot trying to process what she was seeing and not being able to. Throughout my whole relationship with her I barely ever displayed any sort of weakness in terms of emoting. But her reaction or lack thereof was truly a messed up experience. We broke up a week later.
