It's just not healthy to spend the rest of your life chasing after somebody who simply isn't interested being with you.
So at some point you will need to move on.
You realize that there's more to life than the man who broke your heart. You realize that if it really was true love, it will always find its way back.
You allowed yourself to be sad, but you also gave yourself a deadline.
You wallowed in your bed as much as you needed. You cried until your eyes hurt, until there are no more tears left inside of you. You gave yourself time.
Now that the storm has passed, you're beginning to see the light again. Inside you feel calm and more like yourself. Your self-respect grows. You're no longer driven by reckless emotions that have caused you to be careless. You truly feel like a changed person.
One day he's going to realize that he lost the one person who is willing to sacrifice their own happiness for them. One day he's going to realize that he lost the person who will give them the world. One day he's going to wake up and realize that he should have tried. One day he's going to realize that it's a little too late to take you back. You were worth the fight. You always were.
