Disappointment- The feeling of sadness or displeasure caused by the nonfulfillment of one's hopes or expectations
It's scary giving someone your trust knowing that doing this could cause nothing but sadness for you. i longed for this day and yes i was disappointed.
Having you're hopes up is like a game of Russian roulette.
you have you really trust to find the outcome. It really is a pisstake, i mean you feel like a total idiot. the anger just stays with you without you even knowing until one day it's burst. Burst at the most wrong time and then and only then will the weight on your chest will finally disappear.
knowing that you can't trust them makes you think whether your respect or even love for them really exist. They could leave you with nothing and not even look back, there's always a risk.
