The predicament of Honesty

The problem of coming clean, admitting your faults, your feelings, and your fears is the idea of change. Yes we are all scared of rejection, and the idea of admitting your faults or feelings or fears the person you admit them too wont accept it or reciprocate it, however, more then that I believe we are scared of what is to come after you do so.
For instance, many of my friends have come to the conclusion that my situation with Mr. Big has gone way to far and it is time for me to admit to him that I have developed feelings and we need to ether a) move forward or b) stop. However, i do not really like this idea. For the reason, yes I am petrified of rejection, but more so of what comes next. The idea of change. If/when he tells me he doesn't want anything more, I have to move forward. I have been stuck in this one spot for so long that i don't know what else to do. the idea that me and him will probably never talk again like we used to, further more, how awkward it will probably be at school scares me more then his words probably ever could. They would hurt yes of course, but the awkwardness, and change at school scares me even more so.
I know if I don't I'll always wonder what if, which is ten times worse, however, I don't know if i have the courage enough to do that.
the idea of change scares us because it is the unknown, it is unfamiliar, we don't know if we can handle it, or if we will crack under pressure and have to hide. That is why we take the other road, even if it is hurting us because we know that we can handle it. Maybe we finally admit feelings or fears when we realize we cannot handle the road we are on anymore. We've reached a dead end and the only way to freedom is to turn?
