This is for some (including me) a very recognizable scenario and I've been on both sides. The side where you are in power and can get your way by pushing the other away with hurtful words and disregard of their feelings. And they come back each and every time. Two things gradually will sneak up on you. You start to wonder if this is the one and you get used to getting your way.

Until the other side after the 99th time (in the movie) realizes all his tolerance has been used up a while ago and the power plays have been eating away his love. He goes through a transformation in a final attempt to make things work.

The ending is a bit too pretentious. The way the movie is setup it screams for a happy ending, but they leave things in the realm of possibilities. I had to subtract two points for an otherwise very well written study of this kind of (destructive) relationship, because it was unsatisfying and the "we want to do something else" sauce was dripping all over it.

Overall it was very nice to watch, both the light first half, in which there are already subtle hints of impeding doom. And the second half, where so many things were recognizable. Things you don't anticipate when you are the other.
