I heard this quote from a friend today and it put a lot into perspective. Women are pressured to look at relationships in terms of lost opportunity rather than sunken cost, and to question what we could have done better rather than what the other person has done wrong. We shouldn't be questioning relationships based on what we are not doing right or lost opportunity with others, but we should be tallying the resources that we are putting in.

Time is our most valuable asset; we can always make more money, more friends, and find things to make us happy, healthy, and safe. If someone is wasting our time or affecting our health, then they are taking something from us that we can't get back. You may regret hurting a friend, quitting a job, or building debt, but these are all things that can be resolved with hard work and time. Chances are that you will most regret sinking your energy, mental labor, time and resources into a relationship or person that took you for granted when you could be bettering yourself or the people around you.
