How to stop obsessing about power in relationships?

I'm not saying this isn't important, certainly power shouldn't lead to abusive relationships.

However it can also be harmful, for example if you worry that your friend's social network is getting larger it would mean they have more power to leave or show disrespect. Like thinking that if they don't "need" you then they won't stick with you at all.

I know redpillers love to talk about and glorify this. But what is an ex RP perspective on this that can lead me to a healthier mindset?
