Picture the following dialogue in a tense relationship:
A: Look, if you were different, things wouldn´t have got this bad. Sorry, but this is your fault: you are so stubborn!
B: You are so right. Now that you say it, I can see that it really is my fault. I am going to work on it from now on. Thanks for telling me and helping me improve.
Does that sound familiar to you? Unlikely. In real life, statement A will not lead to statement B.
