Perhaps you are tempted now to get back in contact with your ex, breaking the no contact rule.Your minds working overtime.
You were friends - you justify - I miss him.
What will one phone call do?
We can be Facebook friends surely?
I’m over him enough to become friends. Hey, no strings attached. I can handle it.
What if he wants to get back together?
He needs to know that I am around and available.
These thoughts are all completely normal after a breakeup, its just part of the process of splitting up and missing them.
Does your heart tell you that there is no way back? If so keep strong with your no contact. Try to focus on negative memories just as much as the positive ones - get some balance. And remember you can't be Facebook friends, or have sex with them, or have friendly chats. You must stop all contact now, today and not tomorrow and accept someone better will walk into your life.
On the other hand does your heart tell you that you miss them and desperately want them back. There was no violence in the Relationship and you are willing to work at whatever problems you had. If this is the case, help is at hand, its not too late.
