If you feel like you're not being treated right in a relationship, give some serious thought to how you want to handle this situation before reading them the riot act. Consider the true value that this relationship has in your life: is their behavior truly a deal breaker? Or should you just let it slide? Consider the dramas going on in their life: they may need you to cut them some slack. 'slack,' after all, is a unique gift that friends need to give to each other, sometimes.
