Considering getting back with an ex partner after a bad breakup can mean a lot of changes for both of you if you want to make the relationship work this time around.
When one person has walked away from a relationship and then realizes they have made a mistake or would like to give it another shot, it may take a while for the relationship to get back on track due to the bruised ego of the other.
It is important not to allow things to be the same as they were before you broke up the first time. If one of you has an explosive temper for example, hopefully the time away from each other has changed that kind of attitude. If one of you was a frivolous spender, hopefully you have learned that you need to get your finances in order before you decide to get back with your ex. Likewise, if it was your ex who was spending frivolously, would you be able to put up with that if they do not want to change?
