Quote: When does is the line between hope and being pathetic. Between perserverance, conviction, and obsession. How do you let go and still hold on to the pebble? Unrequitted love is like a disease
I think that the line is when you focus your energies primarily on your W to the exclusion of the rest of your life. You don't have to let go entirely, but you need to redirect towards yourself. If you can't find the way to be content without her then your odds of never being with her are greater.
Quote: I want to move on with my life. But still decisions that I make still factor kim into them. "if I do this and kim comes back, then what effect will that have" "If I do this then, it will make it harder for kim to come back to me"
And therein lies a big problem--putting your life on hold on the off-chance that she'll come back. She doesn't have input in your decisions anymore. Getting a life is about you. Do the things you want to do without considering her wishes. Seeing you being happy and content with your life is much more attractive. Look at it this way...before she came into your life did you consider "what if some future woman I want to marry doesn't like this?"
Patience is a must have, but make sure that you aren't patiently waiting for her to come back while you don't do anything for yourself.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
