You end up spending so much time and energy trying to 'make it up to her'
I haven't lost a single power struggle in my current relationship because I learned to not play them. Here is the thing. Somebody in the relationship is going to feel more secure. Right at the beginning of this relationship I established that I would bounce at any moment without second notice and without remorse or sadness. Total detachment. So instead of trying to play power struggles with me, it's already understood that I hold the power. She thinks she wants to be with me more than I want to be with her. That may or may not be true in reality, but it's true in her mind. And I don't have to put up with 90% of the bullshit most guys who don't understand this principle do. I've never "made up" a single thing to her because she can't convince me I messed up.
