Getting heart broken is inevitable, getting over it is hard. It takes several steps, however, there is no definite way of getting over it.
Drown yourself in all the good times you had. I know this seems negative but it is not. By remembering all the good things you used to do together, you are allowing yourself to feel and let go at the same time. It is hard to remember all the good things that the person who broke your heart did and said but try, allow your self to feel.
After getting the good things, cherish the precious memories. One day, someone else will make you feel better that your ex, but none will be like those already experienced. This does not mean you are not taking a step to healing, you are and in the long run, learning how to still have the charm you have always possessed. These memories will teach you that each day is special, even though it ends up badly. When a child is removing her tooth in infancy, the pain is unbearable, but when at night the tooth fiery leaves money where the tooth was, she wishes to feel the pain again to get that happy again. Lock them away and thank fate for giving you the chance to be happy, at that time.
Get out the bad memories, all the sadness you have inside of you. Do not coy away from the pain, feel it as you felt the happiness, you are only being human by feeling it. The bad memories will let you know if it was right you broke up with him or her or if it was a blessing for you that he dumped you.
There are two sides to the coin, if you dumped him, it could have been your mistake to do so. Review all the pros and cons you had considered while dumping him and if they still seem strong enough to you, let go.
You can let go by first removing all the things that make you want to go back to him. However, if something is special to you, leave it, it does not mean you are weak or not recovering from the break up.
Next, fill your time with things that you have always wanted to do but could not because he was in you life. These things will make you realise how much you were missing while with him and then you enjoy them to your fullest.
Start doing things that single ladies or men do. Go out and come back exhausted, flirt but do not get involved too quickly, you will be using that person to get over the heart break. Drink yourself stupid and dress the way you want. All these will help you get back to the life you heard, before she or he walked into your life and turned it upside down.
After getting over the heart, learn that it is normal to love and not be loved back. Learn that heart breaks are normal, even in marriages. After getting that fact, protect your heart dearly, but not too dearly to make the one who would make you happy go. When a new person comes into your life, give little til you learn that he will not step on your heart. When that happens, move heaven and earth to make it work, even when you fell it is falling apart for when it does finally fall apart, you would have given it your best, it simply was not meant to be.
Lastly, learn to love and cherish your life. Heart breaks are inevitable, but, practise makes perfect. After nursing one, it will not be hard for you to get over the next, God forbid!!
