After your break up, you will no doubt have a huge battle within yourself.
Your heart is breaking and all you want to do is try getting your ex back, but your mind is telling you differently.
This of course, causes so much confusion inside you, that, in the end you really don't know what to do.
Your emotions are starting to take over, and will probably make you do something that will ruin any chances of getting back together again with your ex.
You have to be strong and force yourself to think rationally.
Do what you KNOW is the right thing to do, not what your heart wants you to do in order to heal.
The only way you are going to heal is by giving yourself time to get over the trauma of your relationship falling apart.
Stay away from your ex at this stage, you will only be more hurt when he/she becomes angrier with you every time you contact him/her.
Being told to stay away from your ex right now probably seems like ridiculous advice to you, but it is the one way that you will actually have a chance of getting your ex back into your life again.
After a little while, when you are over the hurt and devastation of the break-up, you will realise the logic in the advice to stay away from each other.
Of course you will feel lonelier than ever now without your ex, but rather make a point of being around your friends instead of sitting around being miserable about the situation and constantly thinking of how to go about getting your ex back.
Hopefully your ex will be doing exactly the same as you, and after a short time you and he/she will be ready to have a friendly chat to solve the problems that were the cause of the break-up, and talk about the possibility of getting back together again.
