Fuck no. That'll be the worst thing you could ever do

It depends on the reasons why the relationship ended
Personally i'd never go back to an ex. If he didn't fight to make the relationship work the first time , then I'd be concerned that he'd leave again when we faced challenging situation.
If I was the one who'd left him I'd still never go back to him. I'm not indecisive. Once somethings ended then it's over for good for me. Life is meant to be travelled forwards , not backwards.
