Power in Relationships

It never occurred to me that the person with the most power in the relationship is the one with the least investment in it but it makes total sense. If you are the person who doesn't care you will do whatever you feel like doing because it's of no consequence to you whether the relationship ends or not. If you are the one with the least power that means you are highly invested in making the relationship work so you let te other person get away with things that in other relationships they probably couldn't. It's very sad and makes me wonder how many of the relationships I am in or the relationships I see are like this where one person cares and the other doesn't so the one who doesn't gets rewarded. It's something to look out for that I never considered before.
