Is it normal to never talk to your ex again?
Yep.Totally normal
Yes. Plenty of people never speak to an ex again, especially when distance helps them move on or the relationship ended badly.
Absolutely. You don’t owe an ex an ongoing friendship, and going no-contact can make it easier to heal, keep clear boundaries, or simply get on with your life.
Some exes do stay friends, and some need to keep in touch because of kids, shared responsibilities, or a mutual social circle. Neither choice is automatically more mature—the right amount of contact is whatever feels healthy and workable for you.
