I'm sincerely sorry if my observation is a miss here. And also for trying to read the situation, as I know nobody likes to be a matter of discussion like this. So why do I do it, because it helps me understand things around me - I'm addicted to this stuff. It's nothing personal against anybody.
This is what I've gathered thus far:
The relationship never really seemed to have worked flawlessly, "it was hell" all along. It wasn't discussed, it just dragged along until a culminating point was reached.
How it went down, more or less (I could be wrong, of course):
Rather simple actually... I feel like none of the problems or needs were discussed. It seems like you, OP, had it your way almost the entire length of the relationship, with her occasionally trying to have it her way, but which was met with a conflict or a sort of hit to the health of the relationship.
The more she did that, the more paranoid you became, the more aware she became of what's holding her back/what she had been missing from her side of things. Conflicting interests, more or less (again, which were not brought up nor discussed, so they grew ever bigger and more obvious).
I can only imagine how both you and her were feeding this problematic confliction. You, OP, by having prejudices each time things didn't go your way (because by this time you had become used to the way things were, primarlily your way), and her, because she talked about what you 2 didn't talk about with her colleagues, to whom she must've told the twisted truth (because, we are humans, and that's how we tend to express ourselves, by aplifying what troubles us, irrationally at that), who then advised her accordingly to the best of their abilities (but of course basing their suggestions on what she said and how they might have interpreted the situation - this is how she herself has probably convinced herself that you're the bad person, because it's only the reflection of what people to whom she talked to made out of her initial stories and other cues).
At this point, both sides are concinced of the opposite side being the bad one. This too will only grow bigger, no matter how much either side tries to fake it not growing.
That's it from me...
Again, sorry for this... Hopefully you can throw this my observation to the trash can if you did talk about problems deeply every now and then OR when in your culture having a... um... obedient woman or women for a partner was the norm.
I'm no expert. (just an enthusiast?)
And again, no offence. I can't even imagine what the real story is (the objective one) and how much suffering is involved.
Completely wrong.
Thanks though.
