Personally, I don't but I do end in good terms with them.

I have stayed too long in a relationship and it ruins any chance of being on good terms afterwards. It really depends on the WHY you broke up, if it is something fudamental like cheating no second chances but if it is a factor like something needs to change then just maybe but as I said I am wrong person to ask because someone made promises to me and didn't keep them.
I think it is an individual decision when all is said and done, everyone has their own little set of rules/dealbreakers - Some just seem stricter than others from the outside.1
