1. Go no contact
In order for your Ex to come back to you they first must have to miss you first. Distance does not heal all wounds but it does make the heart grow fonder. Do not message them. Do not text them. Do not email them. Do not call them. No matter how much you miss them. Do not contact them.
2. Play it cool
Do not make any drastic moves. Do not post pictures to make them jealous. I can promise you that after they break up with you they will be stalking your profile even if they were mad at you. Give yourself dignity, grace, and respect! Relax!
3. No drama
Your Ex will begin to do things to spark some kind of emotion from you because they are going through a whirlwind of emotions for dumping you. All these things are actions to try to get over remorse and pain. It also might be a sign that they are still not over you. It basically might be a sign that playing it cool is working. Do nothing. Continue with your life. Let them continue doubting their decision.
4. Keep it classy, keep it polite
When you are trying to get your Ex back you are trying to rekindle the warm feelings that were once lost. What you must do is to try your best to ensure that all interactions that you have with your Ex are positive. Be warm and friendly. Keep contact short.
5. Spark jealousy with the appearance of moving on
Make yourself less available. Find a new hobby. Look and appear busy. Make your life appear exciting. Date too!
5. Transform yourself
You must find out what went wrong in the relationship. Find out what they did wrong to be able to communicate what your needs are. Find out what you did wrong and change who you are. Have you ever imagined what it would be like to have sex with a person you once dated again? Now..imagine you see that person a year later after theyve gone to the gym and they have a nice toned body.
Become the picture of that person you want to be. Have an answer that is more than just "nothing much is new..."
