What is a one-sentence summary of the following article?
Erase your ex's number from your phone completely and you'll be less likely to send a text. If you try, you'll scan your contacts, not see their name, and instantly be reminded that texting them is a no-no. You can also try putting the person's number on your phone's block list, especially if there's a chance they may reach out to you. When the urge strikes to text your ex, reach out to a friend or family member instead. Let this person know what's going on and have them distract you from the impulse.  Say something like, “Today would be our anniversary, so I'm tempted to text. Convince me to change my mind, please!” Let your friends know that you may need their help with this while you recover from the breakup. For example, you can say, "I often want to text my ex. Can you help me when I'm feeling tempted?" You and your friends might even devise a code word that you can text them when you're upset. For example, you might text them "ex alert" or a certain emoji. If you're feeling particularly weak at any given time, surrender your phone completely. Hand it over to a friend or family member until the urge fades. Thanks to technology, you can call in reinforcements to help you stop texting your ex. Scroll through your smart phone's app store to check out the available breakup apps. Download the app and use it until the urge to text your ex fades. Certain apps, like Ex Lover Blocker, are designed to limit your ability to reach out to your ex by calling your friends whenever you try to make contact. You might find that you are able to keep thoughts of your ex at bay during the days when you're otherwise busy. However, you might be tempted to reach out at night when you're bored or lonely. If this is the case, shut off your phone for a few hours each night and spend time doing nourishing self-care activities instead.  Watch your favorite movie, study, read a book, or paint your nails to occupy yourself each evening instead of using your phone. Let friends and family know of others ways they can reach you if they need to, such as through email or instant messaging on your computer.

Summary:
Delete your ex's number. Call or text someone else. Give your phone to someone else. Install a breakup app. Power off your phone in the evenings.
