There is no reason for soon to be exes or exes talking to each other unless they have children. Of course you could be on talking terms so if you run into him in a grocery store you can say hello. Not talking doesn’t mean being nasty. But other than that there is really nothing to talk about. My ex husband is not a bad guy and we get along but we only maintained connection throughout the years because of our daughter and he is the father of my daughter’s younger siblings. We keep in touch only for that reason. Otherwise we’d have no reason and no interest to ever talk. What about?
