While you could argue that this movie is filled with clichés, let's be real and even if it doesn't apply to yourself admit to ourselves that things like this happen. And the way the actors portray their roles is just incredible. There is not much in the romantic department here, that might feel "right" to those who want a rather smooth movie, without any edges.
But if you want "reality" and people going with instinct (and doing a lot of wrong things), this drama delivers fully. It's tough to really root for the characters, but that's not the point here. And it's not a blueprint on how to do things. But maybe you can learn a thing or two from the mistakes being made here and try to work things out without stepping out on your relationship. So maybe there is something useful there after all ... But that's up to you to decide.
