Girl... late reply I know... but hey...
Hang in there, will you?
Look, destiny and heartbreaks are two different topics... but let's talk about destiny...
Have you looked up ancient texts or philosophical references on destiny? even the Vedas say so... quite interesting I tell you... it involves science... some myths and mysteries... but does destiny really works?
Was he meant to hurt you? yes
Is it your decision to turn the outcome to positive vibes? yes
Were you equally responsible for what happened to you? Yes-No, this statement is totally situational, why you ask? because.... in every situation, every min, the decisions you make leads you to your current moment... when something "wrong happens to you unintentionally done by life/nature" that is also destiny but humans develop certain empathy and that's called sympathizing with a "victim of situation or whatever"
Look, we're a victim to horrible events in life and we're victims to how we treat ourselves too.
Is that boy worth your attention? No
But, if you still proceed to think about him rather than working on yourself n move ahead... that's destiny telling you that you're stupid.
Destiny is in your hand.. balanced by destiny created by nature which is a parallel universe and does not overlap each other... some of it is your doings and others were meant to be... have a little faith, will you?
