So here you were, practically balling your face off, and then you stumbled on this article.
You want to get your ex back, that is obvious, and probably in the back of your head you are thinking your case is hopeless! However, I want to stop you right there, because once you use these psychological tactics, your will pull your ex back once and for all.
Remember that it's not hopeless, but it's hopeful, as long you do the right things to win your ex back...
Date someone and take them to places that your ex frequents- When your ex sees you with someone else, he/she will burn madly inside.
Your ex will immediately want you, because he/she would see that someone else has you.
People want what they cannot have, and on top of that, your ex would fear that he/she is about to lose you forever.
This is the golden nugget to get your ex back: simply make your ex jealous! Fix your mistakes- We all go wrong here and there, but to continuously keep making the same mistakes over and over is just plain silly.
Find out why you broke up in the first place, and look back on all the things you could have done differently.
Improve as much as you can in these aspects, so that you do not go back to your ex exactly the same as you were when they wanted to break up with you.
Make your ex forgive you- You may have tried to do that, however the only way you can really do this is to agree that you were wrong.
Next you must show them that you understand their pain.
Say something like "I understand I hurt you, and I had no right to do that to someone I loved".
Afterwards you should assert that you do not actually expect him/her to forgive you.
This will make your ex feel obliged to, since you are no longer forcing it, and you seem to understand his/her pain as well.
