Everyone keeps telling you to let go of your relationship and move on. How can this possibly make you feel better when your Ex is the only thing that matters to you? If you are hurting as much as I imagine you are you need to do something to help your self; you need to get control of your emotions before you can start to feel better. Only once you have passed the "Roller Coaster" stage can you start to think straight and see things as they really are.
So how do you get past the immediate shock and pain of a break up? You simply have to make the decision everyone is advising you to make; i.e. let go and move on. This is probably the exact opposite to what your emotions are telling you; more than likely you feel going back is the only way to make you feel whole again. Let's look at this logically for a moment before continuing; I'm going to make a few assumptions here, only you know if they are true.
You feel gutted by your break up.
You feel getting back with your Ex is the only solution.
Your Ex holds the key to your emotions and happiness.
Your Ex does not want to continue with the relationship or you called it off because you were unhappy with certain aspects of the relationship.
You have tried to resolve the situation but it didn't work out.
You are probably having great difficulty communicating with your Ex.
I could go on but I'm sure one, if not all of the above apply to your situation. So what's my point? There is no solace in going back and there is no happiness to be found at this juncture in talking to your Ex about your relationship. The only way you are going to start to recover is to come to the painful realisation that your relationship is over for now. Why do I say for now? No one knows what lies in the future, you and your Ex may rekindle your love at some later stage but for now you need to become whole again. You need to close this chapter of your life and look forward with excitement to your new future. You are where you are, accept it and move on. You will also be much more attractive once you get your self confidence back. Give it a go; it works. Let go.
