Double Standard

I have a friend who is very much into double standards. How do I get this person to understand they are behaving this way? Whenever I try to explain the situation, the person gets mad and turns it on me and won't accept any personal faults. All faults are mine. I in turn get defensive. How do I break this cycle? I don't want to lose this person as a friend.

What is special about this person as a friend?

This friend sounds rather selfish. You could try explaining, perhaps write it all in a card?
If this person is hurting your feelings and will not compromise it might be time to move on.

it looks like you should not deal with this person unless you can find some way to have them see it your way too.

If you've tried to explain it and they won't listen then there's nothing else you can do. If you want to maintain the friendship you just have to accept them as they are. People don't like their "flaws" being pointed out to them. If they ever come to you for advice, or ask why you think something happened then you might try pointing it out again but generally people don't want their shortcomings pointed out to them.

Pretender 79, are you pretending? If they argue and do not want to change, then what makes you think you can change them? You cannot. So if they will not change, are you willing to put up with them for the sake of the friendship or do you want better and feel you deserve better than that? God, grant me the serenity, to accept the things i cannot change, courage to change the things i can, and the wisdom to know the difference.
So, do you need to change your friends? Or your attitude in accepting them as they are? Blessings.

All very good points, thank you all for the advice. This gives me something to think about, I may just have to learn acceptance
