I have been through a heart break ample of times and the last time I went through it, by God's grace, it was far more painful than ever before. Here are some things I did to get over him.
Ø Do those same activities with a group of friends, preferably friends of same gender, it helps to disassociate the activity with that specific person, thus you can start to let go, and additionally you bond better with your buddies.
Ø Do some scene, see how they react, their stupid behavior will tell you that you were lucky to get away.
Ø Concentrate on your life; make a list that you want to improve in it.
Ø Start doing things that you wanted to do but could never do because of them.
Ø It’s perfectly natural & OK to be angry for a while. Get angry, break things, throw stones, and be mad. Don’t worry, things do settle down in some time.
Ø Make new friends who don’t know what has happened and at the same time make a pact with yourself that you will get over that shit and so don’t discuss anything with these new friends.
Ø Learn to be in the moment. Don’t use phone/ internet when you are out for some socializing.
Ø Act crazy, do bizarre things but make sure you don’t do anything that will harm your bright future.
Ø Do those things which that person said you shouldn’t be doing.
Ø Make sure that you manifest Happiness in your life. Keep reminding yourself you will be happy no matter what and be in charge of your happiness. You may even change your passwords which will reflect positivity.
