If this person will no longer be part of your life, you should delete their contact information. This might help prevent you from calling, texting or emailing them.  You might remember their phone number or their email address, but removing them from your phone, computer, tablet, address book etc. can make it at least a little bit more difficult for you to quickly contact them. For example, if you delete your ex’s contact information from your phone, it’ll be less tempting to just tap their name and send a text or give them a call — at the very least, it’ll make you think before you do so. If the person still calls or texts you, if you have a smart phone you can download an app that blocks their calls and texts so that you don’t receive notifications. Doing this is particularly useful if you’re working hard to keep your mind off of them, as every time they call/text you’ll be reminded of them, and you may be tempted to respond. If they often contact you via email, have their messages immediately directed into a separate folder instead of your inbox. You can do this by creating an email filter — directions on how to do this will differ depending on the provider. If you’re struggling to get over someone, having them on your Facebook, Twitter etc. is a terrible idea. Instead of just deleting them, block them; this way, you won’t see anything that they post, and vice versa. It may be tempting to see what the person is up to on Facebook, Twitter, Instagram or some other social media site. Avoid the urge to check up on them, as this will only make it more difficult to get over them and move on with your own life. Delete old texts and other communications such as emails, FB messages, WhatsApp chats etc. You have better things to do with your time than pour over those old messages and feel upset. Before getting rid of photos, think about whether they depict a part of your life that you really want to forget forever.  As time goes on, you might look back on the relationship or at least the time period in your life...
