I am continuing this here again as in my previous post the char limit got over.
Once you open your eyes u will see the dif. You will see that when you went back in time from the situation of pain due to ur GF to the point of time where there was no such pain, u will realise that U were enjoying life and even your GF is not indispensible. Basically our brain knows that our GF is not indispensible and we can enjoy life without her too with some better girl. Its just that our heart does not listen to our brain during such times. Once ur heart knows that all was well in past, you will come out of your grief much early. If required do this exercise morning and evening each day.
And remember, no body is bad, its the TIME which is bad. Destiny rules, U were correct in that. Butt here are way which we dont know, I found this way accidently and IT WORKS.
