When your heart is broken, do you heal yourself and not let anyone else in? Or do you leave it out there in the open, exposed and vulnerable?

Withdraw and let it heal itself. I don't leave it out there open and vulnerable. It's a deeply personal thing and a long process for me.
I only put it out there in bits and pieces to express for catharsis. I can't imagine splatting it out to strangers. It's too intense for one thing.
