Guys and Girls :how do you think I should deal?

Let's say you been ha boring this crush on this guy name Jeff for six years, but it just so happen that Jeff was married when you met and you didn't have a clue. He was just joking with your feelings and ever since then your luck in love just went down like the Titanic. You hold it in, write silly love songs, poems, stories and cry as much as you can, but you still can't get over him. How do you deal with such a heartache? Do you think I can heal with heartache?
