Women (especially significant others) tend to want you to agree with them, not with the person they're complaining about.
Don't give an objective analysis of the situation with an account of the other person's point of view, especially if your wife or girlfriend is in the midst of emotionally venting. It won't be appreciated.
Once she's cooled off and feels listened to and heard, then you can start to reintroduce logical analysis and 'what was the other party thinking and why did they do what they did'. But not right away.
