Think about what makes up the substance of your relationship. If the substance is sustainable and firm enough of a foundation to build a future upon, keep contributing yourself to it. If the substance is teetering its balance enough to survive the next tiff while shopping in the grocery store but screams of a threat for break-up at the next moment the other person is 'too much' or 'too little' of 'this' or 'that', do not lend your time to making healthy something that is sick and does not want to become better.
