Summarize:

When you really miss someone, it's hard to resist the temptation of texting them every second of the day. But if you do, they don't really have a chance to miss you. Put your phone on silent, so that you don't hear it buzz when the person texts you. That way you will take a bit longer to respond. You can also leave your phone at home when you go out with your friends, or turn it off when you're about to watch a movie. Taking breaks from your phone will mean that the other person has a chance to reach out to you first, and you won't text back quite so fast. If you're in the habit of posting every minute of your life on social media, try easing up a bit. They'll miss you more when they don't know what you're doing every minute of the day. Also avoid liking and commenting too much on their posts. For your own sanity, try to resist endlessly scrolling through their social media accounts. If you can't resist, at least don't leave a tell-tale trail of likes and comments behind you. If you get a new haircut, or a cute new outfit, send a picture to your special someone, and it will make them miss you. This is an especially powerful tactic for long-distance romantic relationships. If you want to make it less obvious, send a picture of you hanging out with your friends, and say what a fun adventure you had. Just make sure you look cute in the picture! Don't wait for the conversation to fizzle out or the other person to hang up because they have somewhere to be. Instead, end the phone call by saying you've loved talking with them, but you have somewhere to go. Make it clear that you still care about the person by ending on a positive note, but still leave them wanting more by initiating the goodbyes. When you speak to someone before meeting up again, make a promise to do something special together. Then they'll have something to actively look forward to and they'll be eager to see you again. Consider keeping the actual event a secret. Simply say that you have plans for when you meet up, but don't go into too much detail. The element of surprise should increase the anticipation and the other person's eagerness to see you.
Put your phone on silent so that you aren't texting them constantly. Avoid posting too much on social media. Text or message them cute pictures of yourself. Be the first person to end the phone call. Make plans to give the other person something to look forward to.
