My ex can't get over me, what can I do?

To be honest, that seems like your ex's problem, not yours. If they are frequently contacting you, block them. They need to take care of their own "stuff," not make it your burden.

It's can be because they are really in love with you and you keep just trying to hide. That encourages longing and is quite hard to get over. Don't text them., or change your number/block. Let it get really boring then one day turn up at their house and in no uncertain terms tell them you are NOT in love with them, and that is that, and that you won't answer them anymore. Showing up startles them so take the higher ground for a moment1. If they are sensitive drop a letter. I mean, use the appropriate level of force to make them understand that's that. Men always know how to keep winding you back in and use manipulation. So, if you can't use enough force and then completely cut contact, or feel endangered tell someone, even the police if you have to.

Your ex cant get over you. Ask some questions to yourself. Are you giving him/her opportunities or hints to stay in hope for you? Did you clearly tell your ex that you don't have feelings for him/her. Are you done with him completely? Is there complete cut off or are you guys still in contact? Or he or she can't find a replacement? Answer lies in these questions. Sometimes we unintentionally make things complicated for us and for our partner too. Complications keep us haunting and make us vulnerable until we take a clear, bold and final step to set others free and of course ourselves.
