If you make the decision to leave, be willing to accept the consequences of your action. Don't attempt to abandon serious conflicts. They will not abandon you. Avoiding Avoidance is one of the most common strategies for coping with conflict or potential conflict. Avoiding is a legitimate strategy when you need time to cool off, when you stand to gain nothing from confronting a situation, when power is drastically unequal, when you want to put distance between yourself and the other person, or when you need time to prepare.
Avoidance buys time.
Use the time wisely once you have it. For example, if you postpone a meeting, immediately get to work, prepare yourself, and reschedule. If you avoid a confrontation over a significant issue, make an alternative plan for addressing the issue and follow through. For example, you might decide to avoid a conflict with someone you've just met because you don't want to jeopardize a brand new relationship. That's fine, but if the issue is important it will come back to haunt you, so don't be caught unawares.
