Do you think getting back with an ex is a dumb decision?

Weither it was a good or bad breakup, wasn't the first waste of time enough evidence of incompatibility, why do people feel hopeful it will be any different the second time, mostly if the breakup was a petty breakup. I might be wrong but didn't the majority of successful relationships never have a breakup? They stay together, it's like getting out of a fire alive and walking back into it šŸ˜‚
