Why is it always unbalanced?

In relationships where both are NPD or both are some type of cluster b, why is one person seemingly always having to compromise for the other? While the other doesn’t?

Is it just about perspective?

Is it just about power dynamics?

How can things be more balanced in a partnership such as that?

What is the issue there? If both are NPD or both are cluster b shouldn’t both feel more equal?

I mean, both trigger each other’s deepest wound(s) and feel very similarly, but it always seems that both run each other around in circles and there’s constant misunderstandings that seem to have simple solutions.

Are they both just blinded by their own shit?

What do y’all think?
