There is no set of formula to get your ex back once the rose tinted glasses are washed away and all the headiness has gone out of a relationship.
If you have been dumped and you know that most of the blame is yours, and you want to have your loved one back in your arms, you have to try some bold moves which might help you get them back.
Physical Appearance Looks do matter.
So take care that you don't turn into a shabby shadow of your former self.
Your ex must find you looking better than when the two of you were together.
So splurge a bit on yourself.
Get a new wardrobe or a haircut.
Hit the treadmill.
The compliments you receive from others will boost your self esteem and will also make you attractive to your ex once more.
Mental Make up Take hold of your emotions and analyze your mistakes.
Try to remove them and start afresh.
Don't ever let your ex have the pleasure of seeing you moping around.
Instead, your mental strength should make them admire you.
Maintain Some Contact If you severe all ties with your ex, you will only prove it that any contact with them makes you feel bad about yourself.
What you need to do is that you maintain a cordial relationship without any emotional hang ups.
You may need each other's help in professional or social matters.

Socialize Friends, especially mutual friends can be very helpful at such times.
So spend some time with them and whenever possible, let your friends know how much you miss your ex or how you have realized your mistakes and still want to be back with them.
Your sincerity will turn your friends into your advocates and they will persuade your ex to take you back.
They will even you give you suggestions about what you can do to get close to your ex again.
