Maintain a relationship at any cost. But what is this cost?

Maintain a relationship at any cost. But what is this cost? It is too expensive. The price of this relationship is you, your soul, your life, and everything you wanted. To maintain a relationship that is falling apart means making all the concessions, agreeing to any terms, breaking yourself. The price is you. Preserving yourself is much more important and valuable. And by the way - cheaper. Because the price of keeping you is the loss of the person who wanted to break you.
