You harden up with each experience. They sting less and less as time goes on
Time helps us get through pain, even though it often leaves a mark. For me, changing how I think about things has really made a difference.
It's great to feel good, but I don't think that needs to be the main goal of life. I try to see life as a gift where feeling all kinds of emotions is a valuable part. I hope everyone gets to feel the incredible joy of being in love and the comfort of a happy relationship, but also knows what it's like to go through a heartbreak... Because going through different feelings, good or bad, adds so much to our lives.
Heartbreak gives us strength and empathy, happiness gives us beautiful memories, and love? Love is that quiet, steady thing that makes all the tough parts worth it. So I try to welcome every feeling, every moment, and every experience, because together, they make up our unique, stories.
If it was true love, that heartbreak will never go away. But you're not fated to love one and only one person. Take some time to get yourself together, probably a couple years, and then put yourself back out there. You'll find someone who will love you, and whom you love, just as much and who won't break your heart.
You start to feel less intense emotions when you get older. Same reason why you'll never get that Christmas morning excitement again.
"The pain I feel now is the happiness I had before. That's the deal." - C. S. Lewis
Inherent in any great joy is the eventual pain of its loss. Even if we were all immortal, everything changes, nothing gold can stay. Your options are to love and grieve, or to cauterize your emotions and go through life a grey husk.
In my experience the suffering of losing a romantic love is less intense the second time, but the falling in love and passion can also be less intense and take longer to build up as you're more guarded with your heart after being heartbroken before.
After you've had the Ultimate Love Affair that has broken you, leaves you certain love has been poisoned in your system, then, and only then, can you be saved and uplifted by the Post-Ultimate Love Affair. - Harlan Ellison http://www.baen.com/Chapters/ERBAEN0072/ERBAEN0072.htm
