If you truly want to win back the heart of your ex, you have to be able to combine being honest with indifference perfectly.
If there is still love between you and your ex, this combination will rekindle the love in such a way that you will not believe.
After break ups, we are naturally depressed especially when it is your partner who ends things.
You feel so betrayed and yet craving for the person.
You wish you can get the person to change his or her mind immediately.
It's impossible, trying to achieve this by persistence will only worsen the situation of things.
This is why you have to show apathy.
It is great if you had a shot at apologizing before or during the break up, but if you didn't it can hold.
If you try doing this after the breakup has already occurred, it will seem like you are frantic about getting back with the relationship.
Take some time off, you don't have to travel, just stop the communication between you two.
Make new friends and boost your social life.
Try to occupy your mind, you could make new hobbies, probably learn to play a different musical instruments.
All these will not only help keep your mind occupied, but will add some value to your life.
During you time off, your ex might give you a call, but if not it doesn't mean a thing.
If you feel you are not ready to speak when you get the call, don't pick let him or her drop messages.
Listen to the messages and try to discern the person's motive.
Whether or not your ex sounds apologetic, don't jump into conclusions.
Just be you and honest.
If you have anything to apologize about, do so briefly.
Sound caring but not overtly caring.
Be wise in your combination of these two things.
Know when to say the truth about the fact that you want to get on with the relationship and when to leave things as they are.
This combination works like magic but you have to be careful with the application as if you sound too honest, you will be taken for granted and if you are too indifferent your ex might drift farther from you.
