Most Helpful Guy
I think it make no sense to go back to something that didn't work out because they are still the same person with the same issues that caused the break up. It could work if they broke up for a reason that wasn't really a reason to break up. Exp. breaking up with a woman for leaving your hair in the sink or breaking up with a guy for not letting down the toilet seat. Reasons like this can easily be fixed.
Now, if a person has been working to change and get help to work on their issues that cause the break up , then it can be worth another chance.0
