Answer:
Unrequited is it...? Sure you have the time to mope over it right? Spend that time getting over it. If it's truly unrequited then there's nothing you can do about it, but are you sure that this is so? If there were no bad or sad things in this world I'm sure every second wouldn't be as sacred as it is. You have nothing else to do about it. It's your choice whether you want them to know your feelings or not, but if you do not let them know you have no way of knowing if it is really unrequited. Take this from someone who has made the mistake of assuming. If you are rejected then move on. I know it's hard but holding on to something broken is harder, and it'll only continue to cut you up until... there is nothing left.
