<human>: Give me a shortened version of the text

So I have known this girl for about 3 years, in that time we have both been in and out of relationships. We have always been somewhat drawn to each other as friends, and we have always stayed as just friends, helped by the fact we have both never been single at the same time.

So recently I have started to really like this girl, and really desire a romantic relationship with her. We talk a bit, and really get on well, we see each occasionally, but as she is approaching her final exams for school she has little free time.

I know when it comes to relationships she is somewhat reserved, and doesn't like to let her true emotions show, and it is exactly the same with me. Furthermore we have both been hurt in the past. However, based on how she acts (and I'm an optimist) I seriously doubt that she has any romantic interest in me, and I don't blame her, I know i have been friendzoned big time. 

having made every attempt I can to get out of the friendzone and make my feelings known, nothing has changed, leading me to my question: in the off chance she hasn't realized how I feel, or is waiting for me to make some move, should I tell her how I feel (obviously in a tactful way) and risk making our friendship somewhat awkward for the next few months (we also work together in a somewhat social job). Or should I just knuckle under and move on.
<bot>: really like a girl but I have every reason to believe the feeling isnt mutual, having tried everything should I tell her how I feel, or leave it alone?
