Some things are not better the second or third time around!

Why do people work so hard to get an ex back?  Clearly, you all broke up for a good reason, so why go back down that road.  Some things are not better the second or third time around.  The time a person spends trying to make things work could be spent on trying to find someone new and better.  Why try to fix a situation when you can go out and get an upgraded version?  Most things in life turn out to be a lesson learned; therefore, once we learn we should apply it to something new.  I don’t know about you, but I like to leave my past where it belongs, in the past.
