That really really really sucks, first off. Secondly, if you would like to progress with your life, but feel that you can't get over this situation under your own power, by all means go to somone who can help you through. Unfortunately when we love someone there is no guarantee they will love you back, and this was shown to you in the most painful way. This girl seems to be perfectly happy with her EX, considering (from what you said about that letter you gave her) that she's very oblivious to your feelings. Sure, she's great and sweet, but the more you center your life around her, the less likely it is that you will "get over" her. Go to counseling, start a new hobby, go to the gym on your lunch break instead of going out to eat with her. Meet new people WITHOUT the intention of "hooking up"- just be yourself. I mean, she likes you, so you're not some total loser, so you shouldn't be approaching life with that attitiude. I'm really sorry you got your heart broken, because everyone can sympatize with that, but it'll heal, you'll learn some things, and one day love will find you, break those chains that bind you.....
