Tolerance or Self-respect?

Tolerance and self-respect have both been part of my pursuit. But now I wonder if it is self-derogatory to tolerate someone beloved who’s been offending your attempts to patch things up. What do you choose then - tolerance or self-respect? If you have the capacity to love some people so much, is it not unfair to deprive yourself of that love? Is it justified to treat your self-respect any less important than the ego of anyone else?

I have seen enough of people doing the unjust in similar situations. Parents wailing for the grown-up children who just don’t want to return, women sobbing before their husbands to abandon the mistresses, and guys shedding blood for their ex-girlfriends. All that disgraceful struggle and pain arises when one side is trying much harder than the other. It makes me believe that a relationship that cannot survive effortlessly will and must come to an end.
