With that said I want to focus on the fact that we are the rules not the exceptions and if we are the exception the person we are an exception to the rule for will let us know we are the exception not the rule. Our friends cannot tell us we are the exception to the rule because the truth is they are just trying to spare our feelings.
When reality finally hits, and with all the bs it hits hard, we tend to get mad at the person for us not being the exception, but that is in no way their fault. After all we do not force ourselves to have exceptions to our rules right? Here is where the ranting comes to the point of clarification. We need to stop building fantasies in our minds and live in the reality. Does this mean that you are not going to be upset or hurt from rejection? I am not exactly sure, but I don't think we will fall as hard.
Now I am not saying give up on liking someone until they clarify for you that you are the exception. I am saying take a chance, flirt a little, then leave it up to the other person. Do not build the fairytale in your mind of how it will end because chances are it will end and it will not end the way you want it.
