The main confusion here is your use of unsuitable metaphor - people choosing that a political bloc is not behaving in a way that they believe represents their interests is in no way analogous to an abusive partner beating his/her significant other, and it is pretty addled to even make that comparison. Yet paradoxically sensible, because it demonstrates why the political process stalled as that framing really is what is in the minds of the EU bureaucrats towards the UK now. You’re also overlooking that 49% of the voters in the UK voted to stay in the EU.
