You let them know it's over and that you won't be communicating in any way. Say good-bye and then cut them off.
Yes unless children are involved it is best to completely cutting the person off
I think its better to cut off communication and move on
If you feel that they don't genuinely care, then I don't see any reasons why you shouldn't just cut off ties. Sometimes you just have to think of yourself and what is best for you :)
No problem. You can still care for someone but if it's hurting you or causing you inner turmoil I just wouldn't bother with it and it would make me want to move on…to protect myself really.
When something's are over I usually change everything to avoid any communication. What I mean by everything is this: I change my email, phone number etc.
a relationship is only over if both parts agree that its over...
