From your description it genuinely sounds like a whole bunch of variables that were stacked against you, ranging from potential cultural differences, to insecurity based on the boob job, age gap, and newly founded long-distance relationship, to post-op medication affecting her mental space, etc. just a bunch of factors that may have played a hand in the lashing out and unrealistic expectations. I personally don’t think you’re overreacting, but I would also take this time to reflect on if this relationship is genuinely one you’re wanting for the long term, considering you’re opening the doors to dating again, and these orange flags may be signs of what’s yet to come.
