I don't think love is the right word. 

How to explain this ache -  

The dull twist, the squeeze, the things that people do to each other. 

Love doesn't feel like this. 

This is the regret when my heart has held on for a very long time, and doesn't want to let go. But just because it is this kind of feeling, doesn't make it love. 

"Do not fear the pain of regret." You said. 

Maybe I'm not the only one. 

Maybe having regrets also means I tried for something. Maybe even held it. Experienced something. And maybe let it go. 

Maybe this is just another part of the human experience. 

Roll with the punches.
